Upgraded Littoral Perrys

Once upon a time, the US Navy faced a choice about how to deal with the fake ‘littoral’ issue (see, “LittoralWarfare – Is There Such a Thing?”):  either upgrade/modify the Perry class frigates or build an entire new class of ships, the LCS.  One required new hulls.  The other required only upgrades of existing hulls.  Of course, the Navy being the Navy, unhesitatingly opted to build new LCS hulls, thereby ensuring their continued shipbuilding budget slice.  In order to eliminate the possibility of anyone suggesting that Perrys could be upgraded for a fraction of the cost of new construction, the Navy neutered the Perrys by removing weapons (2003 timeframe) and stating publicly that it was not possible to upgrade the Perrys to use the new SM-2 missiles that were then coming.  In addition, the Navy wound up giving away Perrys in order to irretrievably remove them from possible service.
 
The USN had decommissioned 25 "FFG-7 Short" ships via "bargain basement sales to allies or outright retirement, after an average of only 18 years of service".[1]

Of course, as is so often the case, the Navy was quickly proven wrong as the Australian navy proceeded to upgrade their Perrys (the Adelaide class) to use the SM-2 and, in fact, added an 8-cell VLS in the bow of the ship.
 
Not only did Australia upgrade their Perrys and continue to operate them but so did quite a few other countries.  Let’s take a look at some of the upgrades performed by other countries after the US Navy stated that upgrades were not affordable or technically feasible.
 
 
Australia
 
The Australian Perrys (Adelaide class) received an extensive upgrade in the mid-2000’s.  The program cost around A$1.46B to upgrade four Perrys (A$365M ea).  Following is a partial list of the upgrades.[2]
 
  • Added 8-cell tactical length VLS in the bow for ESSM missiles
  • Upgraded to use SM-2MR Standard missiles
  • Switched to Eurotorp MU90 Impact torpedoes
  • Upgraded fire control from Mk92 Mod 2 to Mod 12
  • Replaced sonar with new Thompson (Thales) Spherion Medium Frequency Sonar
  • Upgraded Phalanx CIWS to Block IB
  • Added Link 16
  • Upgraded computers
  • Upgraded SPS-49 and SPS-55 radars
  • Added Radamec 2500 EOTS long-range passive TV & infrared surveillance
  • Added laser rangefinder.
  • Added multi-sensor Radar Integrated Automatic Detect and Track System (RIADT) for improved target detection, tracking, and engagement, particularly against low altitude targets in cluttered ocean or near-shore environments
  • Replaced SLQ-32 EW system with Elbit (EA-2118) and RAFAEL (C-Pearl)
  • Added ALBATROS towed sonar
  • Added two RAFAEL Mini-Typhoon 12.7mm remote weapon systems
  • Added additional decoy launchers

Taiwan
 
  • Added 8x Hsiung Feng II/III SSM in two box launcher racks
  • Added 2x Bofors 40 mm/L70 guns
  • Added 2x Type 75 20 mm/75 guns
 
 
Spain
 
  • Replaced Phalanx CIWS with Meroka 20 mm CIWS
  • Replaced SLQ-32 with Nettunel Mk-3000 EW suite
  • Added RAN-12L/RAN-30 air search radar for low horizon scanning
 
 
Pakistan
 
  • overhaul of all four diesels
  • replacement of sea valves and air conditioning
  • new bridge and navigational suite
  • composite dome over the overhauled AN/SQS-56 sonar array
 
 
Following are some other countries that have operated Perrys although I could not readily find lists of upgrades:
 
Poland
Turkey
Bahrain
Egypt
Philippines
 
 
Discussion
 
It is clear that the Navy lied when they stated that the Perrys could not be upgraded.  They simply wanted to ensure that no viable option remained that could derail the – even then – controversial LCS program.
 
Looking at the list of upgrades proves that we could have added racks of Harpoon anti-ship missiles, VLS cells, added more guns, and upgraded almost every weapon, sensor, and piece of equipment on the ship.  In short, we could have had a very powerful littoral combat ship worthy of the name that would have put the LCS to shame and all for a fraction of the cost of the LCS.  This is all the more disappointing when we note that many of the Perrys were retired after only 14 years or so of service.  We had serviceable ships, viable upgrades, acceptable costs, and we chose to scrap the entire Perry class and build the LCS … just a monumentally stupid decision.  And, of course, we are now early retiring the LCS which simply emphasizes and compounds the near-criminal stupidity of the Navy.

  1. Well, if we'd take up CNOs thoughts on non-CVNs having a 20year.life cycle, the Navy could have their constant new ships!!
    But that aside, along with the obvious mental deficiencies of those in charge... I wonder if the Ticos for instance, would be worth a complete RCOH level overhaul? I've read that the Navy is looking at retrofitting SPY6 into older Burkes, so why not ships with the extra vls and AAW Cdr facilities? I understand that much of the mechanical and structural parts of the ships have been neglected for a decade, since the Navy has been trying to shed them that long. But right now there's what, 20 ships lying around awaiting their end? We talked about wanting to see SECNAV and SECDEF make bold moves... so how about decomming every LCS by months end, and cut orders for the crews to report to the mothball fleet to begin reactivation and eventual comprehensive overhaul?? Funds can be found by cancelling the Connie immediately. Even at a $1B each overhaul, its cheaper than the absurd new FFG, and half the price of a Burke, for a better ship!
    ( I know, never happen, and it'd be a struggle to overcome the full level of neglect the CGs have faced. And maybe they are in fact beyond saving. But as someone who's restored old cars all his life, I truly believe it when I say, "I have a torch and a welder, so anythings fixable!", and I think that can apply to ships as well!)
