Yes, the above picture is RAN upgraded OHP... our OHP will likely have MK 41 VLS and sonar hull like indicated on various sourse..

8 harpoon
32 SM-2
8 RUM-139
6 torpedos
76mm main gun

woow..

The Mk13 launcher holds 40 missiles (originally 32 SM1 + 8 Harpoon)

IF McInerney and later transferred OHPs were to get Mk41 VLS, then there are essentially 3 options:
1) Complete replacement of entire Mk13 by VLS > at least 1 but more likely 3-4 > some mix of SM2 and ESSM missiles > this is fairly major surgery + you'ld still need to place racks somewhere for some Harpoon
2) Retain and reactivate Mk13 launcher (switch to 32 SM2 + 8 Harpoon) and add 1 Mk41 forward (add 32 ESSM) = The Aussie option
3) Leave whatevers's left of the Mk13 in place, add 1 Mk41 VLS forward > 32 ESSM. The area of the Mk13 could be used to fit either 1x 21-round RAM launcher or 2x4 Harpoon on racks.

I doubt it would be usefull to fit 8x 22km range RUM-139 (VL ASROC): it add no significant additional capability beyond what the 2 shipborns LAMPS helicopters can already do. VLU space is better used for SAMs.

but will they allow pakistan to upgrade this **** ??

any- idea about comparign it to f-22 p , which result in better buy and advance technology?

you are talking about easily 40-50 million dollars worth of upgradtion which is not essential to PN.

2) Retain and reactivate Mk13 launcher (switch to 32 SM2 + 8 Harpoon) and add 1 Mk41 forward (add 32 ESSM) = The Aussie option

This is more of a realistic option for PN.. quad pack Mk41 in 4x2 cells. each cell has the capacity of equipping with 4 ESSM. But PN intention is still ASuW as prime role rather then AAW AShW or multi role frigate like you are suggesting..

3) Leave whatevers's left of the Mk13 in place, add 1 Mk41 VLS forward > 32 ESSM. The area of the Mk13 could be used to fit either 1x 21-round RAM launcher or 2x4 Harpoon on racks.

their are quite alot possibilities you can do.... but then you will be moving away from the real goal point with ASuW as first priority and the limited budget you have.

I doubt it would be usefull to fit 8x 22km range RUM-139 (VL ASROC): it add no significant additional capability beyond what the 2 shipborns LAMPS helicopters can already do. VLU space is better used for SAMs.

Then i dough you are aware of VL ASROC capabilities.. if you want to add SAMs then the out dated air radar on OHP should be also replaced like the aussies did.. and eventually PN will end up spending well over 700 million dollars upgrading this and that on these frigates.. remember aussies spend about a billion dollars 4 OHP upgrades.

Pakistani OHP will be a ASuW frigate while the F-22P is more of a multi purpose frigate.

im pretty much confused what we are getting machinery or oliver hazard perry frigate or both and if both how many we get of each model of frigate

OHP is the name of the Frigate Class & the ship to be transferred to PN of this class is USS McInerney (FFG-8)

 

[Super Falcon]

6 of them and how many pakistan navy is eyeing or do our navy have any plans to buy destroyers

Total requirement of OHP class frigates has been shown as 4-6 by PN, one will be given next year when it gets retired. Problem with this acquisition is OHP frigates will only be available when USN retires any ship, which will take many many years, in my opinion if we do wanna have all 6 frigates, it may take a decade or so for them to get retired & then transferred to PN.

PN not interested in new destroyers but has shown interest & may be some talks have happened for acquiring Type-42 British destroyers soon to be retired.

PN is looking for 4 more frigates, but little heavier then F-22P & seem interested in the Chinese Type-054A & some others too.

To be precise PN has requested for 6 OHP most probably long Hull version. McInerney is long hull.

Problem with this acquisition is OHP frigates will only be available when USN retires any ship, which will take many many years, in my opinion if we do wanna have all 6 frigates, it may take a decade or so for them to get retired & then transferred to PN.

sir g decade is too overly estimated USN are about to retire entire OHP fleet with in 10 years and its likely that we will get our 6 frigate before 2015.

PN is looking for 4 more frigates, but little heavier then F-22P & seem interested in the Chinese Type-054A & some others too.

My guess is most probably a European 3,500-4000 tonne class frigate which should meet our next generation requirement to match IN newly acquired frigates. PN has also shown interests in purchasing 4 more F-22P frigates (3,000 tonne) which will be a bigger version with better technology. IMO the competition is more with F-22P 3,000 tonne vs Type-054A.

i already requested you about this event. can you plaes tell if there is anything like this going on, i man is PN no showing intrest in 8 F22p frigates in two blocks of four ships??
can you also kindly provide some link to the source,,

(VL) ASROC is nothing more than a means to deliver a lightweight anti-submarine torpedo farther out than when fired from ship torpedo tubes. Its a rocket that upon firing follows a ballistic trajectory to its aimpoint, where is releases its payload, the ASW-torpedo, which then descends by parachute (much in the same manner it would if launched from aircraft or helicopter). In other words, ASW capability is essentially the same as the torpedo but over longer range. The torpedo is the same as carried by shipborn ASW tubes and by ASW helicopters. The rocket adds 28 km (15 nm) to the torpedo range of about 11km. Of course, you can use a helicopter to extend range much further out i.e. beyond the range of sub-launched AShMs.

"The RUM-139A is an RUR-5 ASROC rocket with a completely new solid-rocket booster section, for launch from the MK 41 VLS of modern U.S. Navy surface combat ships. In addition to the ASROC's inertial guidance system, the VL-Asroc uses a digital autopilot, which controls the flight path using the thrust-vector control of the MK 114 MOD 0 solid-rocket booster. The autopilot makes the RUM-139 more manoeuverable than the RUR-5, and enables it to fly a shallower trajectory, avoiding errors by high-altitude winds. The range is controlled as in the RUR-5, i.e. by motor cutoff and airframe separation at a precalculated point in the trajectory.
The payload of the RUM-139A is a MK 46 MOD 5A light-weight homing torpedo, which is decelerated and stabilized by a parachute system before it enters the water. It was originally planned to create also an RUM-139 variant with the MK 50 torpedo, but this was cancelled.
Around 1995, the manufacturer of the MK 46 MOD 5A torpedo (then Honeywell/Alliant, today Raytheon), developed a variant with enhanced shallow-water capability, known as MK 46 MOD 5A(SW). Beginning in 1996, U.S. Navy RUM-139A missiles were retrofitted with the upgraded torpedo, and designated RUM-139B. By 2001, all RUM-139As had been upgraded to this standard.
The designation RUM-139C was allocated in 2001 to a VL-Asroc variant carrying the Raytheon MK 54 MOD 0 torpedo, also known as LHT (Lightweight Hybrid Torpedo). The MK 54 is a new lightweight torpedo, which entered full-rate production in October 2004. Integration test and development of the new torpedo with the VL-Asroc will continue through 2005."

It is worth putting in a Mk41 unit in a Perry just to be able to (ripple) fire a mere 8 ASW missiles to a range already covered by twin helicopters? Or is 32 SAMs a better option?

The Adelaide Class upgrade program has a number of elements, but the 3 most important are (1) a new combat and fire control system with an upgraded long-range air search radar, (2) improved air defense missiles, and (3) an upgraded sonar suite that includes both a new hull-mounted sonar and integration of towed sonars into a common data picture.
The “SEA 1390” upgrade of the Adelaide class ships - the Aussie Perry's - does NOT involve a replacement long range air search radar. Rather, the AN/SPS-49(V)4 air surveillance radar is upgraded to AN/SPS-49A(V)1MPU.
The Gun and Missile Fire Control System will be upgraded from Mk92 Mod 2 to Mod 12 variant. A multi-sensor Radar Integrated Automatic Detect and Track System (RIADT) is added to improve target detection, tracking and engagement, particularly against low altitude targets in cluttered ocean or near-shore environments.
