Pakistan and United States sign a contract for the transfer of USS McInerney

the FFG sans weapons and sensors is FOC.
65m is the cost of re-fit of weapons and sensors as per PN requirement.
these ships have the best marine power-plants with long service-levels.

Well, that remains to be seen. May simply be general overhaul and not much else. But my question concerned not the $65m but the $13m difference between $78m payment and $65m 'transfer/refurb cost'.

Pakistan will pay $78 million for 30 year old frigate.......... i think pakistan is capable of making frigates at least if it can build fighter jets

Yeah. Stuff must be useless because its old. Dare I refer to Mirage III service in PAF: 1968 to present (with Retrofit of Strike Element). That's 43 years. And military jets aren't designed to last that long, unlike warships, which are typically expected to last at least 30 years.

i second that, this ship is way to old, even with refit it will only last a max 5-10 years, and even thats pushing it. PN would be way better off get new ships from China.

And that's exactly their role: gap-filler. Untill such time that Pakistan can produce modern major surface combattants itself.

Incidentally, PNs type 21 frigates commissioned 1974-1978 and were sold to Pakistan, which received them in 1993–1994 at the age of 19-20 years old. Today, at age 32-36, they still serve PN well.

McInerney commisioned 1979 and subsequent OHPs will be younger (McInerney belongs to the first 'short hull' flight and subsequent ships belong to the second, 'long hull' flight).

The USN still operate some 30 OHPs. The Royal navy still operates batch 3 Type 42s, which mostly date from 1985 (the 1980-1983 batch 2 decommissioned 2009-2010). Having decommissioned the remaining Tourville class ships (1974-1977) as recent as 2008, the French navy still employ George Leygues frigates dating from 1977–1988.

In 1988, Pakistan acquired eight Brooke and Garcia-class frigates from US Navy on a five year lease. These commissioned 1966-1967 and 1964-1968 respectively. So, they were 20-24 years old at the time. They served in the PN as Badr-class and Saif-class respectively. The lease of the first Brooke class frigate expired in March 1993, the remaining in early 1994. At which time they were 25-29 years old. Several Garcia class ships were leased and sold to Brazil from 1989 onwards, the last of which retiring from active service and being placed in reserve in 2004 at age 40.

Ands those weren't the first (or last!) ex-USN ships: Pakistan employed 6 ex-USN Gearing class destroyers from the late 1970s to the late 1990s (two scrapped in 1994, 4 stil active 1998, one currently still serving in Coast Guard). These were ships originally built in the late 1940s. Commissioned as USS Wiltsie on 1/12/1946, one was sold to Pakistan, 29 Apr 1977 (at age 31); renamed TARIQ. Became flagship of Pakistani navy, 25 Jan 1990 and renamed NAZIM, remained active as late as 1998 (age 52). http://www.globalsecurity.org/military/systems/ship/dd-710-unit.htm

thats a very costly gap filler then lol maintenance is going to be quite high on these ships.

Well, older ships do tend to require more maintenance. But then again, it depends on the ship and if performed locally in Pakistan, this will be substantially cheaper than when performed in the US.

Historical Service Life vs. Estimated Service Life

Sophisticated combat systems must keep pace with advancing threat technology. As the combat systems and the hull, mechanical and electrical (HM&E) systems of a platform age both must be maintained and upgraded, but the combat systems upgrades tend to be more extensive and expensive. Additionally, as ships age, the cost of operating and maintaining the ships can increase depending on the overall condition of the vessel. For example, if a ship has had a number of maintenance actions deferred over the course of its operating life, and it has experienced high OPTEMPO, the cumulative effects on the ship can lead to higher operating and maintenance costs. This must be considered in investment decisions. In making service life decisions, warfighting capability gained from an upgrade is compared to the cost of the upgrade and the operations and maintenance cost of the ship. Unless modernized, a surface combatant class' Historical Service Life (HSL) is shorter than the Estimated Service Life (ESL) established via instruction. For destroyers, HSL is 20 years compared to an ESL of 35 years. In the case of frigates, HSL is 20-22 years compared to an ESL of 30 years

Frigate HM&E and Self Defense Upgrades

In the FY 03 budget submission, PERRY Class frigates will receive HM&E upgrades to reduce their operating costs and extend their service life. Additionally, the combat systems will be upgraded with selected ship self defense technology. These ships with their relatively small crew size and low operating costs provide affordable warfighting capability.

FFG7 Unit Operating Cost Annual Average $16,000,000 [source: [FY1996 VAMOSC]

1995: VAMOSC Average unit operating and maintenance cost for DDG surface combattants : $23 million. FFG7 $17.3 million (source)

[fy 1989-1991]
Average unit O-level maintenance cost was around $2,3 million per year.
Average unit Intermediate level maintenance cost was about $400k per year
Average unit Depot level maintenance cost was about $6.2 million per year.
http://handle.dtic.mil/100.2/ADA272492
That's about $9 million annually.

The long hull OHPs remaining in service besides McInerney are all 1982-1989 vessels. All ex-USN OHPs in foreign service (including those of Turkey, which has decided them to be worth an extensive upgrade) and half the remaining Australian vessels (also deemed worthy of extensive upgrading) are 1977-82 vessels.
