Asalam-O-Alikum,
I have seen and heard that the Agosta-90Bs are quite capable and there AIP gives them a capability which is not present on all SSKs and this technology is new here are some information related to Agosta-90Bs that Pakistan Navy posses:
Introduction:
The Agosta submarines designed by DCN (now DCNS) of France, are currently in service with the French, Spanish and Pakistan navies. The Agosta 90B is an improved version featuring higher performance and a new combat system.
The new submarine features a higher level of automation, which has resulted in the ship's crew being reduced from 54 to 36. Other improvements include a new battery for increased range, a deeper diving capability of 350m resulting from the use of new materials including HLES 80 steel, and a reduced acoustic signature through the installation of new suspension and isolation systems.
SUBTICS command and control system:
The Agosta 90B submarines are equipped with a SUBTICS fully integrated combat system. This is supplied by UDS International, a joint subsidiary of DCN International and Thales, now wholly owned by DCNS. SUBTICS processes signals from the submarine's sensors, determines the tactical situation by track association, fusion, synthesis, trajectory plotting and management and handles all weapon command and control functions.
Torpedoes:
The Agosta 90B submarine is fitted with four bow 533mm torpedo tubes and has the capacity to carry a mixed load of up to 16 torpedoes and missiles. The submarine can be equipped with the ECAN F17 mod 2 torpedo, which is a wire-guided torpedo with active and passive homing to a range of 20km. The torpedo delivers a 250kg warhead to a depth of 600m.
MBDA Exocet SM39 missiles
The Agosta 90B is equipped with the torpedo tube launched MBDA (formerly EADS Aerospatiale) Exocet SM39 missile. Target range and bearing data is downloaded into the Exocet's computer.
The missile approaches the target area in sea-skimming mode using inertial navigation and then active radar homing. The missile travels at speeds over Mach 0.9, and has a range of 50km. Exocet has a 165kg high-explosive shaped-charge warhead.
Electronic warfare:
The Agosta 90B submarines are equipped with the Thales DR-3000U radar warning receiver, operating in D to K bands.
The system uses a masthead antenna array with omnidirectional and monopulse directional antennae and a separate periscope warning antenna.
Sensor suite:
The submarine is fitted with a Thales Underwater Systems (formerly Thomson Marconi Sonar) TSM 223 sonar suite, which includes bow-mounted sonar and towed sonar arrays, SAGEM periscopes and navigation system and Thales I-band navigation radar.
Propulsion systems:
The Agosta 90B class submarines can be equipped with a diesel-electric propulsion system or the MESMA air-independent propulsion system. The diesel-electric system consists of two SEMT-Pielstick 16 PA4 V 185 VG diesels providing 3,600hp and a 2,200kW electric motor driving a single propeller.
A diesel-electrical submarine has to surface to periscope depth to recharge the batteries using the diesel engine, leading to increased risk of detection. The MESMA air-independent propulsion system, being fitted to the Agosta 90B submarines for Pakistan, allows the submarine to remain submerged three times longer.
The MESMA system consists essentially of a turbine receiving high-pressure steam from a combustion chamber, burning a gaseous mixture of ethanol and liquid oxygen. The Agosta 90B's performance remains the same in all other respects, except that the length increases from 67m to 76m and submerged displacement from 1,760t to 2,050t.
Now some about the Agosta-70s:
In 1978 Pakistan contracted with France for 02 Agosta class submarines. These submarines were basically built for South African Navy but were withheld due arms sales embargo by United Nations. These submarines were smoothly and swiftly integrated in the Pakistan Navy fleet in 1978-79. The 02 Agosta submarines significantly increased Pakistans 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.
PNS/M HASHMAT. Pakistan Navy Submarine HASHMAT was commissioned on 19 February 1979. She left France on 1 October 1979 and arrived in Pakistan on 30th of the same month. Since its induction in the Pakistan Navy, PNS/M HASHMAT has always been an efficient unit of the squadron and the Navy. She has actively participated in all the major exercises at home and abroad.
PNS/M HURMAT. Pakistan Navy Submarine HURMAT was commissioned on 18 February 1980. She left France on 11 August and reached Pakistan on 13 September 1980. She was efficiently integrated as the sister submarine of HASHMAT and enhanced the war potential of Pakistan Navy manifold. The submarine has been deployed on various national/international taskings.
So my question was that as we were and are lacking in our naval dominance and submarines are well known as a force multipliers and are quite stealthy, So didn't we uprade these old Agosta-70s with the same electronics and sensor suite that the Agosta-90Bs carry. We had a good amount of money at that time and we can utilize it to upgrade it to complement the Agosta-90Bs, I am sure there uprade would not have taken too long and we can also utilize its old weapons in anti piracy role as well.
