Ingalls Shipbuilding said:DOHA, Qatar, March 26, 2012 (GLOBE NEWSWIRE) -- Huntington Ingalls Industries (NYSE:HII) will participate in Doha's International Maritime Defense Exhibition and Conference (DIMDEX) this week, highlighting the new patrol frigate derivative of the company's proven U.S. Coast Guard National Security Cutter. The patrol frigate could be built at the company's Ingalls Shipbuilding facility in Pascagoula, Mississippi.
"The Ingalls patrol frigate design has already proven its seaworthiness in U.S. Coast Guard service," said Dan Holloway, HII's corporate vice president for customer relations. "Our analysis has shown there are foreign navies with requirements for patrol frigate capabilities and that this particular design will address naval multi-mission needs. The patrol frigate's technologically advanced ship features, coupled with Ingalls' experienced workforce and active construction line, will generate an affordable platform for a variety of potential customers."
In addition to its patrol frigate, Ingalls will highlight its long history of maintenance and overhaul support to the U.S. Navy, as well as its successful experience as one of the primary builders of DDG 51 destroyers.
Ingalls has delivered three National Security Cutters to the Coast Guard, and two more ships are currently under construction.
There are two patrol frigate variants: Patrol Frigate 4501 and Patrol Frigate 4921.
Patrol Frigate 4501 is closely aligned with the basic National Security Cutter hull with limited design changes. The ships are 127 meters (418 feet) long with a 16.5 meter (54 feet) beam and displace 4,600 tons with a full load. The ship has a 12,000-nautical mile range and can operate in speeds up through 28-plus knots. They have an endurance of 60 days and accommodations for 148. The ship includes an aft launch and recovery area for two rigid hull inflatable boats and a flight deck to accommodate a range of aircraft, with twin hangars for storage of one H-60 class helicopter and two rotary-wing unmanned aircraft. The ships are equipped with various sensors and surveillance systems as well as a 57-mm gun, a 20-mm close-in weapon system and six 50-caliber machine guns.
Patrol Frigate 4921 has additional mission capabilities for anti-aircraft, anti-submarine, anti-surface and mine-warfare provided by a 76-mm gun, a 12-cell vertical launch system, an anti-ship missile launcher and torpedo launcher, sonar dome and remote-controlled and manned 50-caliber machine guns.

Hopefully the US Navy will accept this and build a couple of dozen of them to replace the Oliver Hazard Perry FFGs.
