i think Pakistan Navy lacks too much in electronic warefare system in naval war
we have old anti submarine radars
we lack electronic jammers to jam enemy ship and aircraft radars
we lack with new anti submarine helicopters
we lack Awacs for navy but it will join soon

but seriously PN should buy new helicopter like NH 90 and MH 60 Knighthawk which have state of art sonars to detect enemy submarines and very good torpedos

and PN should have some thing like S-2 Viking which jams enemy ships born radars and even ships


i know we have sea king helicopters for anti submarine role but their sonars are not as good as MH 60 has and we need to work on electronic warefare more than conventional warefare

The multi-mission Sikorsky MH-60S Knighthawk is the US Navy's newly designed helicopter, which entered service in February 2002. The US Navy is expected to acquire a total of 237 of the MH-60S helicopters, to carry out missions such as vertical replenishment, combat search and rescue, special warfare support and airborne mine countermeasures.

132 aircraft have been ordered to date. The helicopter began full-rate production in August 2002 and over 100 aircraft have been delivered. All 237 aircraft are scheduled to be in service by 2011. First deployment of the new helicopter took place on board USS Essex, Wasp Class amphibious assault ship, in January 2003 and a number of MH-60S helicopters were deployed in support of Operation Iraqi Freedom.

The helicopter was originally designated CH-60S, as a replacement for the US Navy's Boeing CH-46D Sea Knight heavy-lift helicopters in the vertical replenishment role. The helicopter was redesignated MH-60S as a result of an expansion in mission requirements to include a range of additional combat support capabilities.

Retirement of US Navy Sea Knights concluded in September 2004. By 2010 the MH-60S and the MH-60R, which will replace the Seahawk, will be the only helicopters in the US Navy inventory.

Sikorsky was awarded the US Navy contract to develop the MH-60S in 1997. The production aircraft made its maiden flight in January 2000. The operational evaluation (Opeval) began in November 2001 at the Naval Air Warfare Centre at Patuxent River in Maryland and concluded in May 2002.

In June 2007, the Royal Navy of Thailand became the first international customer for the MH-60S, with an order for two helicopters to be delivered in 2009. They will be used for maritime utility.

MH-60S DESIGN
The structure of the MH-60S is based on the proven design features of the UH-60L Black Hawk and the naval variant, the SH-60B Seahawk.

The helicopter uses the baseline structure of the Black Hawk with Seahawk T-700-GE-401C engines, hover in flight refuelling and fuel dumping. It also has the Seahawk's rotor system and dynamics, including the automatic rotor blade folding system, rapid folding tail pylon, transmission and drive train with improved durability gearbox, rotor brake and automatic flight control computer. The helicopter also uses the Seahawk rescue hoist for search and rescue missions and the naval cockpit doors.

The MH-60S uses the Black Hawk airframe, which provides the larger cabin volume and double-doors needed for cargo and passenger transport, enabling troops to embark and disembark quickly. The MH-60S retains the Black Hawk's provisions for mounting the external pylons to carry stores and equipment, providing added capability to carry out a wide range of missions. The MH-60S has the Black Hawk's 9,000lb external cargo hook, gunner's window, landing gear with tie downs and wire strike protection, along with hover IR suppresser, automatic stabilisation equipment and fuel cells.

New design features incorporated into the Knighthawk include the tail cone bulkhead and the large cabin is fitted with a new cabin cargo handling system.

MH-60 COMMON COCKPIT
The helicopter is equipped with the new glass MH-60 Common Cockpit, which is also being fitted on the US Navy MH-60R, developed by Sikorsky to replace the Seahawk. Prime contractor for the Common Cockpit is the Owego Helo Systems division of Lockheed Martin Systems Integration at Owego New York.

"The structure of the MH-60S is based on the proven design features of the UH-60L Black Hawk and the SH-60B Seahawk."The cockpit includes four 8in x 10in active matrix liquid crystal displays and dual programmable operator keysets. The avionics includes dual flight management computers and an audio management computer. The navigation suite includes a Northrop Grumman (Litton) LN-100G dual embedded global positioning system and inertial navigation system. Telephonics Corp. supplies the communication management system.

The pilot and co-pilot sit side by side on armour-protected seats. A third crew member is seated next to the forward cabin window. The forward hinged doors are jettisonable.

Lockheed Martin was awarded a USN contract in November 2004 for an upgrade which includes the integration of Link 16, a Ku-band datalink and an improved multi-spectral targeting system, MTS-A. MTS-A includes seven fields of view colour TV camera, forward-looking infrared system with electronic zoom, laser rangefinder / designator / illuminator and triple mode avieo autotracker. The upgrade is planned to enter service in 2009. A further contract in September 2005 includes a 12-satellite GPS receiver and ground proximity warning system.

MISSION SYSTEMS

The helicopter is designed in an air transport configuration that is easily modified with mission kits, for example mine countermeasures systems and combat search and rescue kits. The heated and ventilated main cabin can accommodate up to 20 armed troops.

AIRBORNE MINE COUNTERMEASURES
The MH-60S, fitted with Airborne Mine Countermeasures (AMCM) made its first flight in July 2003.

Lockheed Martin Systems Integration – Owego, with Sikorsky, is integrator for the MH-60S mine countermeasures systems which includes: Raytheon Airborne Mine Neutralisation System (AMNS) with BAE Systems Archerfish expendable underwater vehicle that destroys the mines; Northrop Grumman Rapid Airborne Mine Clearance System (RAMICS), a non-towed mine neutralisation system that will clear near-surface and surface-moored mines using a Kaman Aerospace laser target sensor and a 30mm mk44 gun; Raytheon AN/AQS-20A towed sonar with mine identification system which entered production in September 2005; Northrop Grumman airborne laser mine detection system, AN/AES-1 ALMDS, which began low-rate initial production in September 2005; and EDO Corporation Organic Airborne and Surface Influence Sweep (OASIS).

AN/AES-1 ALMDS detects and classifies floating and near-surface moored mines, using pulsed laser light. The ALMDS pod is mechanically attached to the MH-60S with a standard Bomb Rack Unit 14 (BRU-14) mount.

COMBAT SEARCH AND RESCUE (CSAR)
In the combat search and rescue role the MH-60S will replace the current HH-60H starting in 2007. Lockheed Martin was awarded a contract in December 2004 to integrate the armed helicopter mission kit on the CSAR MH-60S.

The kit includes a digital map, AN/AAS-44 FLIR, the electronic warfare self-defence suite fitted on the MH-60R, an additional pylon to carry Hellfire air-to-surface missiles and mk54 digital torpedo, and crew-served weapons, including 7.62mm guns from port and starboard cabin windows and 0.50-calibre guns from port and starboard cabin doors. Development testing was completed in February 2007 to be followed by operational evaluation and service entry.

"In the combat search and rescue role the MH-60S will replace the current HH-60H."COUNTERMEASURES

The MH-60S countermeasures suite includes: Northrop Grumman AN/APR-39AV(2) radar warner, ATK AN/AAR-47V(2) missile warner and the BAE Systems IEWS AN/ALQ-144V(6) Infrared Countermeasures Set.

ENGINES

The helicopter is equipped with two General Electric T700-GE-401C turboshaft engines. The engine is configured with one centrifugal and five axial stages and has a take-off rating of 1,260kW. The helicopter carries 2,233l of fuel in internal fuel tanks. The helicopter is equipped with a Hover In Flight Refuelling system (HIFR) and fuel dump vents.

The Pentagon has initiated the Integrated High Performance Turbine Engine Technology program (IHPTET) with the US Army, leading to the definition of the Common Engine Program (CEP). It is planned that the all-new engine defined under the CEP will eventually be fitted on the MH-60S helicopter.

The engines drive a four-bladed main rotor. The helicopter is equipped with electrically actuated blade folding for ease of stowage of the helicopter on board ship.

The United States Navy operates 113 Viking S-3B carrier-based aircraft in the anti-surface warfare role with secondary capability in land strike support and aerial refueling. The aircraft has all weather capability and is equipped for day and night surveillance, electronic warfare and for search and rescue missions. The S-3B is operational on US Navy Nimitz, Enterprise and Kitty Hawk carriers.

The S-3A Viking, designed for anti-submarine warfare, entered service in 1975. Between 1987 and 1994, all US Navy S-3A aircraft were converted to S-3B with new mission and weapon systems for the anti-surface warfare and other roles. The S-3B has combat proven precision targeting and over the horizon precision targeting capability.

With the change in roles brought about by the end of the Cold War and the reduced submarine threat, the S-3 is undergoing a major avionics and weapon systems upgrade program and the crew is being reduced from four to three - pilot, copilot/tactical coordinator (COTAC) and tactical coordinator (TACCO).

In March 2003, in support of Operation Iraqi Freedom, an S-3B Viking aircraft from Sea Control Squadron (VS) 38, the "Red Griffins", became the first S-3B to attack an overland target with a laser-guided AGM-65E Maverick missile in combat. The aircraft was part of Carrier Wing 2 onboard USS Constellation.

In May 2003, an S-3B, designated "Navy One" for the occasion, transported President George Bush to visit the crew onboard USS Abraham Lincoln. It was the first time a US president had been in an aircraft making an "arrested" landing on a carrier.

S-3B VIKING DESIGN
The fuselage is all-metal fail-safe semi-monocoque design incorporating high strength features for carrier borne operations. Two parallel beams between the tail hook and the forward landing gear form the keelson structure which provides structural strength to withstand repeated loading of carrier catapult launches and arrester landings.

The all-metal fail-safe wings are folded upward and inward hydraulically for transfer and storage in the hangar deck.

The cockpit is fitted with frangible canopies allowing through-the-canopy crew ejection.

S-3B VIKING (FIGHTING REDTAIL) WEAPONS
During 2001 and 2002 the US Navy carried out a development testing program of the S-3B Maverick Plus System (MPS). MPS gives the S-3B the capability to carry the Raytheon AGM-65E laser-guided and AGM-65F infrared-guided Maverick missile and to control Boeing AGM-84H/K SLAM/ER Stand Off Land Attack/Extended Range missiles. 40 S-3B aircraft are being fitted with the MPS (to be designated AN/AGM-32B(V2)) by 2009 and plans are to convert the whole of the fleet.

Using the MPS, the S-3B Viking crew can control SLAM/ER missiles which have been launched from another aircraft in the post-launch phase. Terminal guidance control of the SLAM/ER Missile is through data link with the AN/AWW-13 Extended Range Data Link Pod. SLAM/ER is a day and night, all weather, over the horizon precision strike land attack cruise missile with a range of over 278km.

The Viking S-3B can also deploy the Boeing AGM-84 Harpoon anti-ship missile with an over the horizon range of more than 60nm.

The maximum weapons payload is 1,781kg and weapon options include missiles, torpedoes, rockets and bombs. The aircraft has split weapons bays with clamshell doors. Internally stored ordnance includes Mark 46/50 torpedoes, B57 nuclear depth charges, Mark 82 and Mark 36 bombs. Weapons that can be mounted externally under the wings include Mark 82, 83, 86 bombs, Mark 52,55,56, 62,65 mines, LAU-10C, -68A and 69A rocket pods, SUU-44A flare pods, Rockeye Mark 20 rockets and anti-ship and anti-surface missiles.

CAINS II AVIONICS UPGRADES
To equip the S-3 for its new mission requirements a number of upgrade programs for the avionics and mission systems are underway.

Carrier Airborne Inertial Navigation Systems II (CAINS II) upgrade: this involves the removal of existing CAINS, attitude heading reference system (AHRS), doppler radar and analog flight instruments. The systems are replaced by the Honeywell H-764G EGI embedded global positioning system/inertial navigation system and digital Electronic Flight Instruments (EFI). The upgrade was completed in late 2002.

Communications Control Group (CCG): Lockheed Martin was awarded the contract for the integration of communications and navigation systems, which was started in 1998 and is scheduled for completion in 2005. The aircraft also has provision for a JTIDS Joint Tactical Information Distribution System.

Computer systems: the Lockheed Martin (formerly Unisys) air data computer type AN/AYK-10A(V) is being replaced with the AN/AYK-23 digital Computer Processor Memory Unit (CPMU), to be completed by 2004. The AN/ASW-33 digital flight data computer is being upgraded, to be completed by 2004. The DRS Technologies AN/USH-42 mission recorder has replaced the RO457 video signal recorder. AN/USH-42 records the ISAR radar, FLIR and mission avionics data.

A Ground Proximity Warning System (GPWS) and low probability intercept altimeter for the S-3 are under development.

RAYTHEON AN/APS-137(V)1 RADAR
Sonar sensors, including Hazeltine AN/ARR-78 sonobuoy receiver, Precision Echo analogue tape recorder AN/AQH-7 and Cubic AN/ARS-4 sonobuoy reference system, were removed from 40 S-3B aircraft between 1999 and 2002.

The S-3B is equipped with the Raytheon AN/APS-137(V)1 radar, which incorporates an Inverse Synthetic Aperture Radar (ISAR) mode, and OR-263/AA forward looking infrared system (FLIR).

FIGHTING REDTAILS (S-3B VIKING) COUNTERMEASURES
The electronic warfare suite includes an IBM AN/ALR-76 electronic support measures unit and a variant of the BAE Systems IDS (formerly Tracor) AN/ALE-39 chaff and flare dispenser.

S-3B VIKING ENGINES
Two General Electric TF-34-GE-400B engines are pylon mounted under the wings. The high bypass ratio turbofan engines are each rated at 41.25kN. The integral wing tanks have a usable fuel capacity of 7,192 liters. The aircraft can carry two jettisonable fuel tanks each with a capacity of 1,136 liters on the underwing pylons. A single point for pressure refueling is installed on the starboard side of the fuselage.

If memory does n ot fail me, US had offered viking, but Pakistan had not accepted the offer

[Super Falcon]

i dont think so they were ofered PN we have P3C orion for anti submarine role but still it is old technology compare to indian P-8 do you agree with me that PN should do some thing to come over to this lackness in electrnic warefare

[Zarbe Momin]

Pakistan Navy is far beheind indian Navy in numbers and also in electronic warfare and its going to be major mistake if Pakistan Navy continues to behave like this rather than to buy technology. Furthermore air defence system on Pakistan Destroyers and Frigrates is also not well enough.

[Super Falcon]

yes i agree with you but why these simple things PN never consider even we are not specialist in naval technology but still what we are talking it is very serious thing PNpeople get paid but still they are nuts from their mind if we want to challange IN in future we can only do it with technology IN has numbers but if PN get technology we can give them tough time U 214 is good move but still Pn should consider above mentioned technologies and must buy destroyers not frigates

[JK!]

The job of a the navy is to be prepared for defenc of the nation so I don't think that this is something they would take lightly.

There are plenty of good things coming in to the Pakistan navy including P3C Orions including three with Hawkeye 2000 airborne early warning systems , F22P frigates and U214 submarines.

Destroyers are intended for more of an escort role specifically with large convoys like a carrier battle group.

Therefore Pakistan has no requirement for such ships.

The title of this thread it "PN Lacks in Electronic warfare " yet the first two posts and most of the remainder of the thread have nothing to do with electronic warfare. So, what IS the topic here?

[Super Falcon]

still electronic warefare sir anyway but what about jammers which can jam enemy cummunications,radars,sonars etc these things means very importantin naval warfare in war time it is important too to defend your ships from enemy fighter jets radars and submarines from enemy sonars for doing that we need good jammers which unfortunatly we dont have and it is save 50% of demage from enemy to us by jamming their radars which hawkeye cannot do it single handedly

[Penguin]

ESM: DR-3000S1X which covers the B-K bands was supplied to Pakistan for Type 21 frigates.The DR-3000S1 (ARBR-18) is the new-generation replacement for DR-2000S and DR-4000S. The system is configured with a 40 kilogram amplitude D/F antenna unit, a 77 kilogram receiver, a 47 kilogram processor, and a 75 kilogram control/display console.

In November 1994, the Pakistani navy ordered a total of nine DR-3000 systems from Thomson-CSF. Six systems were DR-3000S1X versions and were intended as part of the re-equipment of six Type 21 frigates purchased from the UK as replacements for the ex-US Navy Brooke and Garcia class ships. The latter were returned when their leases expired. This series of continued orders extended through 1995 with additional contracts from Pakistan (for the DR-3000U). In 1998, Pakistan ordered the DR-3000 for its Atlantic Maritime patrol aircraft.
