Not exactly. But yes they are very similar ships.
The most noticeable distinction is the Bulbous Bow. The BN LPCs have the Bulbous Bow which the PNS Azmat Class lacks.
A bulbous bow is a protruding bulb at the bow (or front) of a ship just below the waterline. The bulb modifies the way the water flows around the hull, reducing drag and thus increasing speed, range, fuel efficiency, and stability. Bulbous bows are used in vessels when:
The length is longer than about 15 metres (49 ft)
The vessel will operate in coastal and deep sea
The vessel will operate most of the time at or near its maximum speed.
Correction friends. After analyzing the facts and figures I have come to the conclusion that BN LPC-M or the Dhaka Class LPC-M and the PNS Azmat class are not of same class of ships. In fact, Dhaka class is far superior to the PNS Azmat class.
The most noticeable Design differences are as follows:
1. Displacement:
Dhaka class: 648 tonne
PNS Azmat Class: 560 tonne
2. Leangth:
Dhaka class: 64 meter
PNS Azmat Class: 60 meter
3. Armament:
Dhaka class: 1x 76.2mm naval gun, 2x Oerlikon 20mm cannon, 8x C-802A AShM, 4x QW-2, 2x Type 730 CIWS, 2 x 6-tube EDS-25A 250mm ASW rocket launcher (18 rockets), Decoy Louncher
PNS Azmat Class: 1x Type 87 twin 25mm gun, 2x 12.7mm machine guns, 8x C-802A AShM, 1x Type 730 CIWS, Decoy launcher
4. Electronics:
Dhaka Class: Type 360 Surface search radar, Type 352 surface search and SSM control radar for C-802A, MR-123-02/76 Fire Control Radar for 76.2mm gun, Type 347G (Rice Bowl) fire control radar for 20mm cannon, LR66 radar for CIWS, ASW fire control system
PNS Azmat class: Type 360 Surface search radar, Type 352 surface search and SSM control radar for C-802A, LR66 radar for CIWS
5. Deck Design:
Dhaka Class: Elevated foreword enhanced for better surface view
PNS Azmat class: Elevated backward sloped
6. Bow Design:
Dhaka Class: Bulbous Bow. The BN LPCs has the Bulbous Bow which the PNS Azmat Class lacks. A bulbous bow is a protruding bulb at the bow (or front) of a ship just below the waterline. The bulb modifies the way the water flows around the hull, reducing drag and thus increasing speed, range, fuel efficiency, and stability. Bulbous bows are used in vessels when:
The length is longer than about 15 metres (49 ft)
The vessel will operate in coastal and deep sea
The vessel will operate most of the time at or near its maximum speed.
PNS Azmat Class: Lacks the Bulbous Bow expressing they are for petroling coastal water lines.
In conclusion, I would say, the Dhaka class LPC-M is much superior to the PNS Azmat class and if BD budgetary allocation allows, then BN should acquire or build more of these Dhaka Class LPC-M to defent the maritime territory.
