What's new

Bangladesh will commission two submarine on 12th March

Congrats. A great leap forward for Banglas, though the subs are junk. :haha:
It's PNS Ghazi... pakistans first sub that blew up after a refit from turkey... Indians say they destroyed it but I go with the facts to think it blew up just like the Pakistanis do... so unLess this sub blows up for whatever reason. It's ironic you calling it a rust bucket. lol :haha:
 
.
2 subs at $200m.
Can't get better deal then this for BN.

TORPEDOES
Eight 533mm torpedo tubes (6 bow, 2 stern), carrying a total of 18 torpedoes in tubes and storage racks. Alternatively the submarine can carry 32 mines in its tubes.
The Yu-4 (SAET-60) is a passive homing torpedo designed to attack surface targets up to 15km at a speed of 40 knots. The high-explosive warhead weights 400kg.
The Yu-1 is reverse engineered from the Russian Type 53-51, which was designed to attack surface targets with a maximum range of 9.2km at a speed of 39 knots, or 3.7km at 51 knots. The high-explosive warhead weights 400kg.
SENSORS
Fitted with a Pike Jaw hull-mounted, medium-frequency for active and passive search and attack. Later Mings are also equipped with a Sintra DUUX 5 low-frequency passive ranging and interception. The Ming has an I-band surface search radar (NATO code-name: Snoop Tray).
Countermeasures include electronic support measures (ESM), radar warning receiver and direction-finder.
PROPULSION
Diesel-electric arrangement, consisting of 2 Shaanxi 6E 390 ZC1 diesel rated at 5,200hp (3.82MW), with 2 Xiangtan alternators and 2 shafts.

not bad for a first timer sub.... and it's not like we are talking about mark1 tank on today's battlefield here! :)

I think,in capability wise these submarine are not much worse than Pakistan navy Hashmat class(Augusta-70) submarine.Although I may be wrong.Can you or @Penguin bhai can enlighten us about whether this is the case?:-)

Type 035 Ming Class

History:

At the end of World War II, the Soviets obtained several German Type XXIs, from which they were able to obtain certain key technologies. These technologies assisted in the design of the Zulu- and Whiskey-class. Further improvements on the design led to the Project 633 (NATO: Romeo), a class of Soviet diesel-electric submarine built in the 1950s. Under the 1950 Sino-Soviet Friendship and Mutual Assistance Treaty, the Soviets passed to China (and later to North Korea) the documentation necessary to produce Romeo submarines in 1963. The Chinese variant is known as the Type 033 Romeo. The Chinese Type 033 incorporated some improvements over the original Romeo, including noise reduction of 20 dB. Sonar on board was also continuously upgraded: the original Soviet sonar was first replaced by domestic Chinese Type 105 sonar, which consequently was replaced by H/SQ2-262A sonar built by No. 613 Factory.

A total of six Chinese Romeo class submarine variants were developed and built in China from 1962 to 1984.:
a) Type 6633 original Soviet Romeo with improved domestic Chinese batteries;
b) new Type 033s, with improved air conditioning and refrigeration capability;
c) ES5A upgraded Type 033 with replacement of equipment of Soviet origin with domestic Chinese systems, including QZHA―10 (Type 779) attack periscope, QDYA―10 (Type 778) general purpose periscope, more accurate Type 801 sonar, wider 15 degree sector scan H/SQZ-D reconnaissance sonar (with Type 105 transducers) and addition of H/SQG-2 ranging sonar, Type 063 communication systems, and countermeasure systems. Additional noise reduction measures were also adopted;
d) Type 33G, essentially ES5A with the incorporation of the capability to launch acoustic homing torpedoes; analog computers installed to achieve automation and speeding up of torpedo fire control calculations previously manually calculated. All Chinese Romeos were converted to this standard (NATO: Wuhan class);
e) Type 033G1, single Type 033G modified to carry 6 surface launched YJ-1 (CSS-N-4) anti-ship missiles (NATO: Wuhan A) and reduction of noise level by 12 dB; and
f) ES5B export version of thee 033G of which primary improvement is the ability to launch wire guided torpedoes and anti-ship missiles (AShM) while submerged. with noise reduction of 20 dB to 140 dB in comparison to the 160 dB of the original Soviet Project 633 submarines acquired by China.

The Type 035 is a heavily improved redesign of the older Type 033 Romeo-class submarine. The first pair of Type 035 boats were completed by 1974. Yet further improvements were necessary and by the early 1980s a new and improved version (Type 035A Ming) emerged and four boats were completed by 1990. During the 1990, 12 boats of the further improved Type 035G Ming were built and commissioned. Improvements were especially in terms of noise reduction, weapons, sensors and crew living standards. Two boats of the Type 035A were upgraded to same standard. The most modern design variant is the Type 035B Ming-class, which features a redesigned conning tower and portions of the hull, giving it a very similar appearance to the newer Type 039 submarines. The Type 035B, of which four boats were built and commissioned between 2000 and 2003, are capable of launching land attack cruise missile from their torpedo tubes.

Type 035: First two unit of the Ming class. The most significant difference relative to the Type 033 Wuhan class is the switch from twin shaft propulsion to single shaft propulsion. The second unit revealed many problems during trials, necessitating a major redesign,
Type 035A: The second batch of the Ming class submarines. The major redesign not only solved the problem discovered in the original 035, but also increased the top speed by 40% (to 18.3 kt). In December 1983, decision was made to stop the production of new Type 033 class boat and replace it with Type 035A.
ES5C: export version of Type 035/035A, with updated fire control system to launch acoustic homing torpedoes. This design was used to upgrade Type 035/035A fleet.
ES5D: further development of ES5C for export, with capability to launch AShM while submerged added. This design was used to upgrade Type 035/035A fleet.
Type 035G: This is the first Type 035 series to have anti-submarine (ASW) capability. The primary weaponry for Type 035G is Yu-3 torpedo. A French sonar (DUUX-5) and later its Chinese built equivalent version were used. The last unit with pennant number 308 was lengthened by 2 meters to add a section for AIP tests.
ES5E: export version developed from Type 035G, with ability to launch wire-guided torpedoes added.
Type 035ET: French sonar system and its equivalent Chinese version on ES5E export version of Ming replaced by a cheaper alternative, developed using Italian sonar systems, notably the JP-64 active sonar and Velox passive sonar of Toti-class submarine. This unit went into Chinese service
ES5F: export version with integrated sonar system that integrates previously separated active, passive ranging, flank (and towed upon customer's request) sonar into one.
Type 035B: Conning tower and certain portion of hull was redesigned, with new structure similar to that of Type 039 submarine. This type was capable of launching land attack cruise missile from torpedo tubes

Bangladesh Navy ordered two 'off the shelf' (i.e. pre-owned) Type-035G submarines from China in 2013, a deal worth $203 million. These boats underwent refitting and Bangladesh took delivery on 14th November, 2016 of its first Chinese submarines, S161 and S162 (ex-PLAN 356 and 357).

The Type 035G includes all improvements made on the original Type 035 in the 035A, ES5C and ES5D variant, and the improvement of 035 relative to 033. It is unclear where pre-delivery refit includes upgrading in the sense of installation of post-035G improvements such as found on ES5E, ES5F and 035B (exclusive structural changes).

Agosta-70

The Agosta–70 are in the active service with the Spanish Navy, Pakistan Navy. They were formerly in service with the French Navy. In 1977, Pakistan acquired two Agosta–70 class submarine from France that were originally designed for the South African Navy. They were deliverd 1978-79 and entered service 1979-1980. France employed 4, which enteres service 1977-1978. Spain built 4 locally, which entered service 1983-1985. The pair of Agosta-70 submarines significantly increased Pakistan’s maritime offensive defense capability due their enhanced endurance, long underwater detection ranges, over the horizon targeting capability and increased firepower. The linear towed array sonar has provided her the flexibility to classify contacts at extended ranges. They employ 533TT (F-17 HWT) wire- guided torpedoes, Harpoon USGW 2 missiles and can lay mines. The Agosta aubmarine was at the time the best conventional diesel-electric submarine.

Navel Sukhois are diff breed of Aircraft altogether with folded wings/tail arrester hooks and other many distinguishing variations from regular version...which we have absolutely 0 use of

True. They also have very strong modified high-spring-rate dampened landing gear to withstand repeated rough landings on carrier decks.
 
.
I read somewhere that BD Navy was not pleased with the level of noice it was making. Therefore during refit it undergone further noise reduction as per BD Navy demand.
 
. .
could you link the source up pls.... thanks!
Sorry I cant recall exactly at the moment. But I remember the source to be one of the more reliable proven ones unlike the fancy ones.

Meanwhile enjoy
2 BD subs waiting to be commissioned.

BD subs to be commissioned.jpg
 
. . . .
that's obviously a temporary set up...while rehearsals are going on for the actual commissioning in a couple of days time. You can see the dias they've set up with canopy.
Our subs are not probably are not operational yet. These twins are sitting at Issa Khan naval base in Chittagong for our PM to go onboard on 12th March.
 
.
Sh Hasina is actually doing a great job for BD military with economy stronger, no conflicts with neighbour India etc She will even win the forummers here in PDF soon with her modernisation drive.
