Oliver Hazard Class Frigate Acquisition by Pakistan

[Penguin]

Since PN OHP will be fitted with BlockII Harpoons the MK-13 launchers will be upgraded like in the case of RAN OHP upgrade plan and eventually adopted more capable medium range air defence missile the SM-2.

Got source(s) on that?

Pakistan to Receive US Frigate
21 April 2010


The Pakistan Navy will receive the refurbished USS McInerney frigate on 31 August under a $65m contract.

Pakistan will induct the Perry Class guided missile frigate into the country's naval fleet as PNS Alamgir.

The vessel will be handed over to Pakistan following the completion of a refurbishment which includes anti-submarine capability in January 2011.

Pakistan also plans to increase a squadron of eight Perry Class frigates.

The 132m-long and 14.32m-wide frigate has a displacement capacity of 4,100t, accommodation for 212 crew and a top cruising speed in excess of 28kt.

Pakistan to receive first of eight US decommissioned frigates in August

news

21 April 2010

Washington: Pakistan is due to receive a refurbished American frigate USS McInerney by 31 August this year. The transfer is part of a $65 million deal signed with the United States government in October 2008.

The contract for the "hot transfer" of the USS McInerney, a Perry-class guided missile frigate, was signed by senior officials of the two countries here on Tuesday. As part of the agreement the Pakistan Navy takes over the vessel on 31 August and subsequently commissions it as PNS Alamgir sometime next year.

''Hot transfers'' take place immediately after a ship decommissions, that is when it is still floating. This, as opposed to ''cold transfers'' which take place long after a ship has been docked at a storage facility for any length of time.

Commissioned in 1979, this old frigate has now been substantially refurbished as an anti-submarine platform. On full completion of the refurbishment programme in January next year, the vessel then sails to Pakistan to join the country's naval fleet.

Pakistani officials described the deal to acquire the warship a major "milestone" towards further strengthening the wide-ranging Pakistan-US relationship.

"The successful completion of this contract will pave the way for acquisition of more vessels of the same class for the Pakistan Navy to raise a squadron of eight Perry-class frigates," a spokesman for the Pakistani embassy said.

"This will greatly enhance the operational readiness of the Pakistan Navy," he added.

The frigate is being transferred under the Foreign Assistance Act and the Arms Export Control Act. Though equipment received from the US under the Excess Defence Article (EDA) arrangement are free, Pakistan has had to bear the expenses for the refurbishing.

Pakistan was designated a "major non-NATO ally" in June 2004 and became eligible to receive surplus defence equipment from the US military.

The Perry Class Frigate

The Oliver Hazard Perry-class frigates were designed primarily as anti-aircraft and anti-submarine warfare guided-missile warships that would provide open-ocean escort of amphibious warfare ships and merchant ship convoys in moderate threat environments in a potential war with the Soviet Union and the Warsaw Pact countries in the 1970s and '80s.

The addition of the Naval Tactical Display System, LAMPS helicopters, and the Tactical Towed Array System (TACTAS) provides these warships a combat capability far beyond what they were originally designed to do. They are well-suited for the littoral regions.

Our navy is in such bad shape but hopfully we will have more ships but its in bad shape

Mods: can we please merge the 400 threads on the McInerney deal?

PAKISTAN TO GET 7 MISSILE GUIDED FRIGATES FROM USA.....NAVAL CHIEF....................NEWS ON TV CHANNELS!!

 

[xyzseaman]

I think its 7 Frigates for Anti-Submarine Warfare, most likely the Mk13 Launchers and it's Harpoons removed; only the OTO 76mm Cannon and 20mm CIWS will remain.

That and probably a Chinese-made Helo (or a Knighthawk?)

Got source(s) on that?

Its my opinion based on educated guess.
Pakistan has recently acquired 70+ AGM-84L (more on order) and no other platform is suitable other then OHP. In order to cooperate Block II harpoons the MK13 launchers will be reinstalled and the FCS will be also upgraded. As far as i know SM-1 are not in production and their capability are very limited thus wont suite PN requirements and they will opt for more capable medium long range SM-2 for fleet defense. I cant find the source but it did mentioned that PN OHP will be enhanced with ASuW capability with the integration of RUM-139.

I am waiting for the day when my prediction comes true.

AGM-84L, you say? That's the airlaunched version. Might I suggest the P-3C is the probable platform for those?

RUM-139 requires installation of a MK41 Tactical VLU, which is a longer version than the Mk41 Self Defence VLU used by the Australians on their FFG-7 upgrade. Not only is this more expensive to fit than appears to be included in the refurb package of McInerney, I doubt it would fit given that the Australian units already have a substantial portion of the shortest of versions of Mk41 sticking out well above the bow main deck.

Use of SM-2 would require firecontrol and combat system changes that not even the Australian have fully adopted yet (and look at the cost of their program)

One reason the USN stripped the SM-1 launchers off the OHPs in USN service is so they can give the spares to the countries that do operate them. Just the SM-1s stripped off the US hulls gives you well over a thousand maintained missiles (25 ships x 40 missiles). That alone can keep the non-US users (5 navies with 16 ships, including McInerney, and ordnance stocks) going for a while. Then add all remaining US existing onshore ordnance stock.

RIM-66E SM-1MR Block VI (RIM-66E-1/3/7/8), VI A (RIM-66E-5), VI B (RIM-66E-6)
Speed Mach 3.5
Ceiling 24400 m (80000 ft);
Range 46 km (25 nm)
Has monopulse seeker developed for Standard missile 2. Compared to SM2, the SM1 lacks command and inertial midcourse guidance (but doesn't need it because of its lesser range)
Hardly to be called NOT usefull to a navy whose longest range SAM is the SARH 18km, mach 2 LY-60, a Sea Sparrow/Aspide derivative. By comparision, the CLOS HQ7/FM90 Crotale derivatie has a max speed of mach 2.3 and a range of 15km and a ceiling of 6km.

Good news for Pak Navy... congrats.

To me the debate is open on what is going to be the eventual shape of weapons and sensor suite on the Pakistani OHP's.

Couple of things are sure to be there:

1. AshM:Harpoons (only four will be equipped with this out of a total of eight)
2. Close in Defence:Phalanx & ???? (RAM ???)
3. AuS/ASW:TACAS & Torps (yet to be defined) only four will be equipped
5. Gun systems: 1 x Oto Melara & 2 x 12.7 DShk
6. Helo System: Not yet defined
Sub Systems:
Torps
AShM
Sonar/Sono buoys
7. Decoy Dsipensers: ?????
8. Sensors/Radars: ????
9. Missile Suite (Med Range): ?????

I have highlighted in blue what I feel is for sure part of the "Hot Transfer/refit."

May be the senior members can start to build upon this if they so desire.

Cheers!

1. No functional Mk13 launcher then no Harpoon (nor SM1). IF PN retires its six Type 21s, 3 sets of 2x2 Harpoon launchers will become available for installation on board OHPs that will be in PN service then. Likewise 3 sets of LY60 SAMs.

2. Phalanx is and remains the standard CIWS on board the OHP, in PN service too.

3. USN OHPs are fitted standard with 2x3 324 torpedo tubes for lightweight ASW torpedos (mk46, Mk50), AN/SQS-56 Sonar, AN/SQR-19 Towed Array Sonar System, AN/SQQ-89 ASW Integration System, two SH-60 (LAMPS III) or alternatively SH-2F (Lamps Mk-I), or equivalent.
TACAS? Towed Array Condition Appraiser System (TACAS) = an apparatus for calibrating or otherwise determining the low frequency operational parameters of an elongate hose-like array. I.e. not a weapon but a maintenance device.

4???

5. 76 mm (3-inch)/62 caliber MK 75 rapid fire gun is and remains standard fit. DShKs are russian 12.7mm HMG's and not fitted standard (but easy to install).

6. Helo's: SH60 or equivalent (click link in item 3).

7. AN/SLQ-32 Electronics Warfare System, Mk36 SRBOC Decoy System, Nixie towed decoy.

8. AN/SPS-49 Air Search Radar, AN/SPS-55 Surface Search Radar,
Mk92 Fire Control System (for 76mm, Harpoon)

9. None.

AGM-84L, you say? That's the airlaunched version. Might I suggest the P-3C is the probable platform for those?

rrrright. I am referring to 60-70 newly acquired RGM-84block II that are launched by Frigates.

RUM-139 requires installation of a MK41 Tactical VLU, which is a longer version than the Mk41 Self Defence VLU used by the Australians on their FFG-7 upgrade. Not only is this more expensive to fit than appears to be included in the refurb package of McInerney, I doubt it would fit given that the Australian units already have a substantial portion of the shortest of versions of Mk41 sticking out well above the bow main deck.

The 70 million dollars pakistan is paying for are not for paint jobs and few nuts and bolt changes. We must not confuse refurbished cobras and F-16 block 15 with this extensive refurbishment for OHP that are customized for PN requirement. PN has operated RUR-5 in the past and I wont be surprised if 8 cell MK-41 VLS is acquired for RUM-139 use. These are anti submarine frigates meaning their prime task is what it is built for, not a 4000+T coastal petrol vessel. IMO either all 8 OHP are to be fitted with MK-41 or 4 and the other 4 maybe utilized for cost effective AAW for fleet defense.

Use of SM-2 would require firecontrol and combat system changes that not even the Australian have fully adopted yet (and look at the cost of their program)

So does the new Block II Harpoon which requires new fire control system. Once the MK-13 and new fire control is installed the SM-2 is all good to go.

One reason the USN stripped the SM-1 launchers off the OHPs in USN service is so they can give the spares to the countries that do operate them. Just the SM-1s stripped off the US hulls gives you well over a thousand maintained missiles (25 ships x 40 missiles). That alone can keep the non-US users (5 navies with 16 ships, including McInerney, and ordnance stocks) going for a while. Then add all remaining US existing onshore ordnance stock.
Has monopulse seeker developed for Standard missile 2. Compared to SM2, the SM1 lacks command and inertial midcourse guidance (but doesn't need it because of its lesser range)
Hardly to be called NOT usefull to a navy whose longest range SAM is the SARH 18km, mach 2 LY-60, a Sea Sparrow/Aspide derivative. By comparision, the CLOS HQ7/FM90 Crotale derivatie has a max speed of mach 2.3 and a range of 15km and a ceiling of 6km.

SM-1 is a one old surface to air missile near to end of its life 25-30 years, and if PN acquires these oldies it will be impossible to operate them beyond 40-45 years of life. SM-1 has no future in indo-pak context against latest Indian AShM and cruise missile acquisitions. Its like PAF requesting US for AIM-54 and AIM-7.
SM-1 is as useless as AIM-54 even though PAF never had a AAM with a range beyond 30 KM.
SM-2 are very essential for PN to defend against IN AShM unleashed upon surface fleet which may only depend upon Phalanx and will give a new decent fleet defense system.
The 100+KM SM-2 may also provide good air support to P-3s against Mig-29Ks and alot other advantages its gonna give to PN.

And how is PN planing to fit those 20 years old 3 sets of 2x2 launchers in 8 OHPs? OHP has enough room to fit 4x4 Harpoon launchers on its deck so why should they be limited to only half of that?
Retaining Mk-13 and updating OHP fire control system will be much more effective then 2x2 launchers.
