The Air War of '71 Revisited
By Group Captain Sultan M. Hali (PAF)
Few nations in their history have undergone so many trials and tribulations as has Pakistan. From its very inception, Pakistan faced wars, insurrection and natural calamities. During all the vicissitudes and adversities that the country had to endure, the Pakistan Air Force bore the brunt of them all.
As we celebrate the Golden Jubilee of our independence, there is yet another milestone which we have crossed. It is the 25th anniversary of the 1971 War. The year 1971 was, in a way, the bleakest period of our brief history when our Eastern Wing was separated form us; 93,000 Pakistan were taken prisoners of war and numerous others laid down their lives in the defence of the nation.
For reasons best known to the powers that be, the causes of the outcome of this war have been kept under wraps. Irrespective of the final result, there were individual acts of valour. The Pakistan Air Force performed extremely well and has nothing to be ashamed of. Therefore we owe it to the families of the Shaheeds and those who fought with indomitable courage, that the details of the war be discussed and credit given where it is due. It is also imperative that the lessons learnt from this major campaign are taught to the younger generation. Many veterans of the 1971 War ask, "Did they fight for nothing?". They must be answered. The Silver Jubilee of the 1971 Air War, therefore, must not remain unheralded.
Backdrop to the War Against Secessionist
A discussion on the genesis of the break-away of our Eastern Wing is beyond the scope of this article. However, it is clear that the events leading up to the separation of east Pakistan from its western half in 1971 will be interpreted differently for many decades not the least due to the fact that throughout most of that year both Pakistan and its enemies reacted to events with such mutual intransigence as could lead to only one end - the dismemberment of Pakistan. Indias collusion with the Soviet Union in 1971, formally embodied in the treaty signed that year between the two states, foreclosed the possibility of Pakistan resolving the crisis arising due to social inequality, cultural variance, topography, physical separation of more than a thousand miles and the consequent secessionist pressures.
India not only fuelled the fires of secession but stage-managed an alleged refugee crisis. The hue and cry it raised about the so-called 10 million refugees who had supposedly poured into her territory - but were never allowed to be visited by any international agency - did not fool even her staunchest supporters. Of the many countries that condemned Pakistans harsh suppression of the Bengalis, none failed to see the Indian forces crossing of East Pakistans borders on 22 November for what it was: a brazen aggression, on the strength of a superpowers backing against a sovereign neighbouring state which had been militarily debilitated by a highly inflamed civil war.
Wars, whether premeditated or fought in righteous defence have, in the end, been judged by the modern world more for their aftermath than the logic of morality.
As the pilots of Pakistan's only squadron in the eastern wing took to the air repeatedly from Dhaka against 10 IAF squadrons attacking it from all sides, these young men were under no illusions about the end. Their spirited assaults upon the Indian fighters over Tejgaon airport were clearly visible to foreign correspondents from the roof of the nearby Dhaka Intercontinental Hotel. Several of the newsmen took pictures and movie-shots of Indian fighters being chased and shot down by the handful of outnumbered No. 14 Squadron pilots who continued, even as their ability to operate from Dhaka diminished with the increasingly cratered runway, to write another glorious chapter of courage and perseverance in the history of the PAF.
Balance of Forces
By 1971, the Indian forces had learnt their lessons well and created for themselves ascendancy, both strategically and tactically, as well as a superiority in defence planning and the higher direction of war. During that year, while Pakistans political leadership was ensnared in a power crisis, the Indians had planned, and prepared with deliberation for an invasion of East Pakistan - with clearly set political and military goals.
In terms of military hardware, the IAF stood fifth largest in the world after the USA, USSR, France and China. It possessed over 1200 aircraft, some of them belonging to the very advanced category and the remainder of substantial capabilities. The inventory of advanced aircraft which were capable of performing multiple roles, comprised of 232 MiG- 21s, 128 Su-7s and 165 Gnats. These were backed by some 300 relatively old but still operational Hunters (199), Mysteres (61) and indigenously produced HF- 24 Maruts (54) . Nearly 85 Canberra night-bombers were also available. Even the obsolete Vampire (224) and Ouragon (50) fighters could be used in areas uncontested by the PAF, to add to the IAFs overwhelming numerical superiority . On the other hand, the PAF too had combat aircraft which could, in performance, match the IAF to a reasonable degree, but the PAF was numerically at a forbidding disadvantage. After 1965, the US embargo had degraded the spares support for the F- 86s, F-104s and B-57s. The dependence now lay on the freshly acquired Chinese F-6s, a short range air defence fighter, and a handful of Mirage-IIIs. The US embargo affected only Pakistan because India got almost all of its equipment from the Soviet Union.
In the interlude between the wars, the IAF had also developed an elaborate airfield infrastructure which, given Pakistans crippling geographic disadvantage of lack of depth, gave the IAF an enhanced capability to reach targets deep inside Pakistan. Additionally, with Soviet assistance, the Indian air defence system had been greatly improved while its terminal defence of airfields had also been upgraded with very effective rapid fire radar-controlled AAA guns as well as surface to air missiles (SAMs).
Thus, the situation in the western theatre was very difficult for Pakistan; while in the eastern theatre it was utterly hopeless in view of the ongoing civil war and the PAFs incredibly small size. Surrounding No. 14 Squadron, the solitary squadron of the PAF, were 10 Squadrons of 203 aircraft of the IAF, comprising of Hunters, Su-7s, MiG-25 and Gnats. There was no early warning system for Dhaka because the PAFs mobile observer units and radar had to be withdrawn from the border and inland locations after suffering casualties at the hands of the Mukti Bahini and armed insurgents.
In short, at the advent of the 1971 war, the odds were set heavily against the PAF. It was pitted against an air force which had an overall 4:1 numerical superiority; and in East Pakistan, this numerical superiority was 10:1, with an elaborate airfield infrastructure and an effective air defence system
Pakistans Military Strategy
The concept of Pakistan's military strategy was that if India chose to attack East Pakistan, we shall, while maintaining a defensive posture there, open a front on the West without delay. As the events unfolded in the Eastern Wing, following the Indian attack in November, the Pakistani ground forces could not put up an effective holding action against the advancing enemy. Nor was a major counter-offensive launched in the West. Even when the much delayed decision was taken to open the western front on 3 December 1971, it was at the insistance of the PAF Air Chief, Air Marshal Rahim Khan.
Beginning of the War in the West
The PAFs Command Operations Centre (COC) at Rawalpindi and all Air Base Command posts had been fully activated on 21 November 1971. When the order finally came on 3 December, the commanders, pilots, engineers and support personnel were so poised for action that its first strike formations were hurtling down the PAF runways within just 20 minutes of the order to launch the air offensive. The formal messages declaring a state of war were still being decoded at the bases when the strike aircraft were returning to land.
In accordance with a pre-planned assault against IAF airfields and radar stations, the first dusk strikes crossed the border at the same time and struck their targets between 1709 and 1723 in two waves with varying intervals. A total of 26 missions with 24 Sabres, 8 Mirages, 4 F-104s, 15 B-57s, 1 C-130 and 4 T-33s, were launched against 14 airfields and 2 radar installations. All aircraft returned safely. The details of the missions are given in Table-1.
The success of these initial raids can best be judged from Indian sources. The most authentic comments emanate from My Days with the IAF written by Air Chief Marshal P. C. Lal, who commanded the IAF during the 1971 war. He would hardly be inclined to exaggerate the PAFs performance. Extracts from his narrative are as follows :
Halwara
"The B-57 dropped 8 bombs, 3 of which landed on the runway, making two major craters . . ." (p.249)
Amritsar
"The attack . . . started with a visit by four Mirages. . . They made 4 to 5 craters from the beginning of the runway to about 600 meters - At 10:10 pm that night - five hourse after the Mirage attack there was just . . . one lane of runway serviceable (when 2 Su-7 pilots) took off in their Sukhois. Immediately after that a PAF B-57 came and dropped bombs." (p.256)
Sirsa
"The PAF B-57s bombing . . . was enough to make the runway unserviceable for the night the bombs had time-delayed fuses and kept on exploding at intervals till dawn, delaying clearance and repair work." (p.271)
Jaisalmer
"One of the bombs hit the underground power cable . . . for the next six hours Jaisalmer operated on its standby generator and was without telephone facility." (p.283)
Uttar Lai
"The runway was bombed thrice on the very first evening of the war" (forcing the pilots to use the taxi way for take off and landing). That is how we operated for the first six days of war." (p.286-87)
Bhuj
". . . the PAF bombed it fairly accurately . . . The Air Force Commanding Officer found it difficult to get together enough labour to repair it." (p.291)
One other IAF source deserves mention by way of tribute to the PAFs B-57 crew who valiantly faced the highest loss rate of the war, and persisted doggedly each night, despite their rudimentary bombs and aiming devices, in carrying the war deep into the enemys heartland. The narration comes from an Indian MiG-21 pilot, taken prisoner after being shot down over Pakistan. Flight Lieutenant Harish Sinhji, who belonged to a Sirsa-based squadron, stated:
"After one of PAFs night bombing strikes on our airfield, we were all gounded for six hours. The runway had been cratered in many places. The next morning our CO took us all to the runway to show us the Pakistani pilots bombing accuracy. 'This is the kind of bombing accuracy the IAF pilots should achieve against Pakistani targets.' the CO said, pointing to the craters on the runway". During the following two weeks the PAFs F-86s, Mirages, T-33s, B-57s and C-130s, (first used as bombers in the 1965 War) continued the bombing campaign against Indian airfields and radar. The IAF was kept under constant pressure, its night operations over Pakistan proportionately inhibited. Ground Action
Minutes after the Mirages and F-86s struck the IAF airfields at sunset on 3 December 1971, No 8 Divisions artillery thundered over the Indian Dharam enclave on the Pakistani side of the Ravi River, and the territory fell to General Abdul Ali Maliks soldiers without resistance. Far to the North, General Akbar Khan was boldly launching his 12 Division towards Poonch, and in Chamb, General Iftikhar prepared to lead 23 Division across Tawi River. As dusk fell in Lahore and Kasur, General Naqvis 11 Division attacked across the border to gain tactical ground. Fierce battles were fought in Hussainiwala and Sulemanki by 105 and 106 Brigades while far to the south, General Mustafa postponed for 24 hours the desert assault of his ill-prepared 18 Division to capture Ramgarh.
The IAF, on the other hand, was preparing to strike back. By 9:00 pm, its Canberras were being revved up for their forays deep into Pakistan, their targets being the PAF bases which had launched the war on the Western Front.
But first to the incredible saga of some 18 F-86 pilots about to write an unforgettable chapter of indomitable courage over Dhaka, as they prepared to fight 200 aircraft with their 16.
Intrepid Under Siege
The flash message, which went out to all PAF bases at 1735 hours on 3 December, must have occasioned wry smiles in the Ops Room of No. 14 Squadron at Tejgaon airfield:
"As of this evening Pakistan is at full scale war with India. Phase three is declared with immediate effect." No. 14 Squadron and all of Eastern Command had, in fact, been in a state of full scale war since 25 March 1971. Of the 1,222 airforce men based in that wing, 645 East Pakistanis had to be laid off duty by April 1971. The PAFs mobile observer units deployed in the countryside had to be withdrawn after 40 airmen and one officer were brutally murdered by terrorists at different locations. After March, the transfer of jet fuel from the Narayanganj depot to Dhaka airfield in bowsers also became impractical and the PAF was forced to use the C-130 in the tanker role; it brought fuel from as far away as Rangoon and Sri Lanka to keep the tanks at Dhaka airfield up. So 14 Squadron had to fight with what it had - just 16 F-86Es, 2 T-33s and 2 Alouette helicopters.
The men of 14 Squadron operated with resolute courage under these grim conditions. During March-April, the Squadron flew some 170 sorties for air support to the army which had become heavily engaged in operations against the Mukti Bahini, and by mid-year had managed significantly to reduce the scale of rebel activity. The Indian high command became perturbed at the quelling of the insurgency. New Delhi signed a treaty of military cooperation with the Soviet Union on 9 August 1971. Emboldened by this, the Indian forces decided to attack East Bengal in the guise of "self defence".
The PAF went into action on 19 November to impede this thrust and flew several missions against Indian guns and troops. It flew over 100 sorties to assist Pak Army units. It was not till 22 November that PAF met any opposition.
At 1518 hours, a flight of 3 F-86s was called out with guns and rockets to the Chaughacha area. Although after 3 attacks the Sabres were running low on fuel, the formation leader, Wing Commander Afzal Chaudhry carried out a fourth attack. During this dive he heard his No. 2 calling out that 2 Gnats were behind him. Chaudhry broke into the Gnats and shot one of them down. Soon thereafter, his wingman again called to say that 2 more Gnats were now in pursuit. Chaudhry ordered a disengagement but when he looked back he could not spot his wingman and saw his No. 3, Flight Lieutenant Pervez Mehdi, ejecting after being hit by the enemy fighters. Both his No. 3 and his wingman Flying Officer Khalil, had been shot down over Pakistani territory but were transported to India after being taken prisoner by the Mukti Bahini.
Operating under these unfavourable conditions, the AOC, Air Commodore Inamul Haq Khan prepared 14 Squadron for its ultimate test. He reorganized Tejgaon's AAA defences, dispersed all his aircraft, and mobilized special runway repair teams of army jawans and airmen. Dummy aircraft and equipment were placed in eye-catching spots at Kurmitola and Tejgaon, while the real hardware was carefully camouflaged.
Hell Hath No Fury
On 3 December 1971, as night fell in the East in the wake of the PAFs opening salvos in the West, IAF Canberras attacked Tejgaon airfield as many as 5 times but fortunately, all their bombs fell wide off the marks and no damage was done. By first light the next morning, interceptors were launched. The first two landed without any contact with the IAF. At about 0730 the third pair led by the operations officer, Wing Commander S. M. Ahmad got airborne with Flying Officer Rashidi as wingman. Though not programmed or required to fly, Ahmad had insisted - in keeping with the PAF's tradition of its seniors leading in combat - and was soon in the thick of battle with 4 Hunters, joined minutes later by some MiG-21s and Su-7s. In the melee, the Hunters' leader shot down Ahmads F-86, forcing him to eject 5 miles from Kurmitola; despite an air and ground search he was never found. Rashidi, in the meanwhile, successfully extricated himself from the 'one-versus-several' situation just as another pair of PAF F-86s, comprising Sdn. Ldr. Afzaal and Flt. Lt. Saeed, was engaging 3 Hunters, a few miles away. Both Afzaal and Saeed were immediately set upon by another Hunter and was himself shot down. Only minutes later Afzaal had avenged this loss by chasing a MiG-21 and shooting it down. Although Saeed had ejected safely, he too was never found; reportedly both Saeed and Ahmad were taken away by Mukti supporters.
The next pair to scramble, Flight Lieutenant Shams and Flying Officer Gul intercepted 2 Su-7s about 3 miles north of Dhaka. The Su-7s were hit but managed to pull away.
At 0940 hours, Shams and Gul scrambled again, this time to intercept two Hunters over Dhaka. Schams fired at the first Hunter and scored hits but since the aircraft did not go down, he went into a dogfight, entered into classic scissors manoeuvres till the IAF Hunter hit the ground , giving no time to the pilot to eject. Gul chased the other Hunter which managed to get away.
The greatest air battle of the day was led again by Flying Officer Shamsul Haq - with the very young but spirited Flying Officer Shamshad on his wing - when they were scrambled around midday. Just as their wheels were locking up, 2, of a flight of 4, approaching Su-7s fired their rockets at the F-86s, which were hardly 200 feet above the trees. Shams broke into them and shot down one of the nearer pair of Sukhois with a Sidewinder, cheered by the squadron airmen watching from below. Shams and Shamshad were next directed towards Kurmitola where each of them downed a Hunter with their guns. Shamshad then returned to land but Shames spotted another Hunter over Tejgaon and fired his second Sidewinder at such close range that before its guidance system could take over, the missile streaked straight into the Hunters tail pipe and blew up its engine. The Indian pilots descent by parachute was in full view of many ground observers around the airfield. But now Shams was in trouble: he was suddenly surrounded by 4 MiG-21s which began to attack him in turn, driving him into a tight corner. The quick-thinking Shams immediately whipped into a max-rate steep-turn at tree-top height, with the Dhaka TV tower in the centre of it, jinking wildly as he turned. The MiGs attack pattern was effectively disrupted and short of fuel, they soon exited the scene.
The IAFs afternoon raiders on 3 December, shifted their attention to the nearby Narayanganj area where the bulk fuel was stored. Squadron Leader Dilawar and Flying Officer Sajjad were scrambled at 1600 hrs to intercept one such formation of 4 Hunters, south of the airfield. Dilawar shot down one of them (piloted by Flight Lieutenant Kenneth Lemontree), then flew headlong into the other pair which quickly broke away. Dilawar then tried to aid his wingman who was being fired at by another Hunter but it was too late. Sajjad also had to eject and both he and Lemontree were picked up by PAFs rescue helicopter. Thus ended the first day, with 14 Squadron pilots having shot down 9 enemy fighters for the loss of 3 F-86s.
On 4 December, Hunters stopped attacking Dhaka airfield and this task was taken up by Su-7s and MiG-21s. 14 Squadron remained busy in providing escort to Pak Army helicopters carrying reinforcements to the Comilla Sector.
On 5 December, Kurmitola runway was cratered by the IAF for the first time and repair work was started immediately. Tejgaon runway and 14 Squadron remained operational throughout the day and the Sabres interceptions forced many IAF raiders to jettison their bombs short of the two airfields. IAF also made a few napalm attacks against the AAA positions and one of the arimens dining halls, causing 5 casualties.
On 6 December, the IAF provided extensive support to the Indian Army in the field. No. 14 Squadron also kept itself available for air support to Pak Army Units. At 0900 hours, a formation of 4 F-86s led by Squadron Leader Dilawar, was dispatched to provide overhead cover to Pak troops at Lakshman, 20 miles north east of Dhaka. The formation engaged 4 Hunters over the battle area and Flying Officer Shamshad got a chance to bag a Hunter when his leader, Squadron Leader Dilawars drop tanks refused to jettison. The remaining Hunters left the scene.
Soon after this formation landed at Tejgaon, a flight of 4 MiG-21s appeared, each dropping 2 bombs. The bombing was accurately executed and 4 out of 8 made craters in the runway. From then on the airfield was kept under regular bombing attacks, severely inhibiting runway repair work. The task was further complicated because the dimensions of the craters were out of proportion to the weight of the weapons delivered. The runway surface was basically World War II quality, patched over and extended to meet the current requirements. The Russian-make 500 Kg bombs penetrated the relatively thin layer of concrete and brick-on-edge soiling, thereby churning up the soft alluvium underneath.
During the night of 6/7 December, the runway repair teams laboured tirelessly and succeeded in filling enough craters to make a 5,000 ft length available. By 0500 hours on 7 December this stretch was cleared and Squadron Leader Dilawar taxied out for an early CAP. Just then another bomber arrived overhead and, in a well-aimed attack, split the usable 5,000 ft almost exactly in half. Dilawar had to taxi back and shut down.
Thus ended the stirring last days of No. 14 Squadron in East Pakistan. Rahim Khan ordered Air Cdre. Inam to destroy the 11 remaining F-86s to prevent them from falling into enemy hands. All the remaining pilots of 14 Squadron were withdrawn via Burma, to continue their arrival at Sargodha. Their Squadron was re-equipped with F-6s. The unforgettable epic of its handful of audacious warriors rising repeatedly from the Tejgaon runway to challeng enemy who outnumbered them 10 to 1, shall remain enshrined in its history for all times to come.
Air War in the West
Drawing its lessons from 1965 war, the IAF had reviewed its target systems and assigned priority to attacking Pakistans vulnerable energy resources (fuel storage tanks, Sui gas fields, oil refineries) and its rail and road transportation system, most of which lay within easy reach of IAFs forward bases. Additionally, the East Pakistani deserters from PAF provided the IAF vital information pertaining to PAFs radar coverage, their blind spots and gaps and exact locations of vital points.
The IAF struck with 15 Canberra on the night of 3/4 December and targeted Rafiqui, Sargogha, Mianwali, Risalewala, Murid, Chandar and Mansoor air bases. On the night of 4/5 December, 6 airbases were attacked, Mansoor again receiving the maximum number of bombs, one of which cratered the main runway and the other destroyed the taxiway culvert. Chandaar airfield was also cratered at two places but both air bases were soon recovered. One of the Canberras was shot down at night by Flt. Lt. Naeem Ata with a missile from his Mirage.
The IAF lost its second Canberra on the night of 5/6 December to Sargodhas AAA gunners. One crater on Sargodhas main runway again forced the base to switch operations from alternative runways. Another bomb impacted on a night engineering facility where Sqn. Ldr. Dar and Flt. Lt. Wasim were working; both embraced shahadat.
During the next four nights, the IAFs night bombing campaign began to decline sharply - a fact not fully explained by the waning moon - and totally ceased during the remaining 8 nights of the war except once, on 14/15 December when only Mansoor was attacked by 3 Canberras, without causing any significant damage. PAF B-57s, on the other hand, continued their nightly assaults against Indain targets without a break till cease-fire was declared.
In retrospect, the Indian night bombing campaign did little to frustrate the PAFs night or day operations.
Battle of the Airfields
On 4 December, the IAF retaliated with force and determination. Using about 70 Hunters and Su-7s in flights of twos and fours, it began a series of strikes against 12 air bases and 2 radar installations of the PAF. Most of the strike routing indicated the IAFs full knowledge-through defecting East Pakistani officers of the numbers, types and locations of PAF radar; this enabled them to exploit the radar gaps and arrive undetected over their targets. This compelled PAF to fly continuous Combat Air Patrols (CAPs). A classic battle took place in the morning near Pimple Hill when a raid led by Squadron Leader Murli, OC No. 20 Hunter Squadron at Pathankot raided Peshawar. Flight Lieutenant Salim Beg Mirza of No. 26 Squadron engaged in a low level encounter which was at timed so low that puffs of dust could rise from the ground. Ultimately, Salim shot down the Hunter and Murli was killed. The same morning Flight Lieutenant Javed Latif of No. 23 Squadron, deployed at Risalewala, alongwith Flying Officer Riffat Munir, both flying F-6s, chased a raiding pair of Su-7s and despite the Su-7s superiority, Javed Latif destroyed the Su-7 over the railway line near Faisalabad while Riffat Munir chased other Su-7 away. On the same day, at dusk, Squadron Leader Ahsan and Flight Lieutenant Qazi Javed were scrambled in 2 F-6s from Mianwali to intercept a pair of raiding Hunters. While the F-6s were still on the taxi- track, the lead Hunter pulled up for attack, squadron leader Ahsan pulled his aircraft of the taxi-track. Qazi Javed, though caught in an awkward position, immediately got airborne as the second Hunter was pulling up for the attack. Despite his limited experience, Javed displayed extreme dexterity and skill. He gunned down the Hunter over Lake Khabakki. Its pilot ejected and was taken POW.
At the end of the day, PAF pilots from different bases had destroyed 10 and damaged 4 enemy fighters while Pak AAA gunners destroyed another 4. In contrast, the PAF lost only one F-86 on the ground at Murid and the radar at Badin was slightly damaged.
On 5 December, two IAF Hunters attacked Sakesar radar. Wing Commander Saad Hatmi and Flight Lieutenant Shahid Raza, flying F-6s, were on a CAP mission. They were vectored towards the incoming raid. Hatmi permitted his enthusiastic No. 2 to lead the interception. The Hunters were flying low and became visible to the F-6 pair only when they pulled up for the attack. The eager Shahid Raza commenced firing from a distance even when the Hunter leader was beyond his range but perhaps his final bullets hit their mark. The wreckage was discovered later. (Shahid Raza was the last casualty of PAF when on 17 December he was shot down by AAA over Shakar Garh, after the ceasefire had been declared). The second Hunter managed to get under Hatmis F-6 and then executing a John Derry manoeuvre tried to get behind the F-6 leader. Hatmi was too experienced to fall in the trap but marveled at the daring IAF pilot. He managed to position himself and shot the Hunter which blew into pieces and fell near Khabakki Lake.
PAF continued its day strikes throughout the war, and in its 100 strikes over enemy airfields and radar, it lost only two aircraft, both F-104s. On 5 December Sqn. Ldr. Amjad H. Khans F-104 was shot down by flak while attacking Amritsar radar and he was taken POW. The loss of the second F-104 occurred when Wing Commander M. L. Middlecoat, was intercepted over the sea near Jamnagar by a MiG-21 on 12 December but Middlecoat could not be rescued by IAF (after ejecting over water). The battle of the airbases raged on but after experiencing heavy losses on the first two days, the IAF switched over greater air effort to interdiction of Pakistans major rail and road communications which run close to the border.
