I always thought that the NSC would make a hell of a nice frigate for many navies (including the USN itself) and of course Northrop Grumman thought so too. Nice stuff, thanks for posting!

Nice.
Looks a far better Perry replacement than anything else, without going to the full expense of a Burke destroyer.

NG has been offering versions of this concept since around 2002 (I remember seeing a model while the LCS competition was just starting).

I found the front of one flier (also c. 2008) that appears to be identical to the International Frigate aside from the name. Can't find the back, but I would guess that it has a Seahawk helo instead of the Lynx and probably no much else different.

Does anyone have any earlier versions of the brochure, especially ones intended for the US market?

 

[blackstar]

I think I have that same flier. They photoshopped the image and I think they used it for the international frigate design, as well as a Coast Guard version as well. I'll look for my copies.

 

[blackstar]

Here they are.

Northrop Grumman has offered its National Security Cutter design as a new frigate for the United States Navy at a cost of less than $400 million as a complement to the Littoral combat ship (LCS), with the possibility of later adding in the LCS weapons and mission module capabilities. The design would have a lower top speed than the LCS but much longer endurance.[10] However the NSC is not built to the same level of survivability as Navy ships and so would face higher risks if pressed into combat duties.

FWIW, NSC was supposed to be built to the same Level 1 survivability standards as LCS (which is lower than conventional combatants) minus shock hardening.

The Huntington Ingalls Industries (HII) PF 4921 is another patrol frigate concept based on the U.S. Coast Guard National Security Cutter (NSC) design.

Close-up of an HII model showcasing the 76 mm gun and vertical launch system of the PF 4921 multimission frigate, based on the National Security Cutter.

On the other hand, the PF 4921 is a light frigate for executing anti-air, anti-surface and anti-submarine warfare. However, it sacrifices range – which is about a third less than the PF 4501 – for vastly enhanced combat capabilities. Armament is a 76 mm main gun, a vertical launch unit for the evolved Sea Sparrow Missile (ESSM), a Phalanx or SeaRAM CIWS, and six crew-served as well as remotely operated machine guns. Mounted aft are two quad packed Harpoon surface-to-surface missile launchers and a triple torpedo tube launcher. Sensors shown on the concept ship include a CEAFAR radar system, a hull mounted sonar and a towed array sonar system. Ship’s complement is 141.

Huntington Ingalls press release:

Huntington Ingalls Shipbuilding Presenting Patrol Frigate Derivative of National Security Cutter at Pacific 2012 Trade Show

SYDNEY, Australia, Jan. 30, 2012 (GLOBE NEWSWIRE) -- Huntington Ingalls Industries (NYSE:HII) will present a new patrol frigate derivative of the company's proven U.S. Coast Guard National Security Cutter at this week's Pacific 2012 International Maritime and Naval Exposition (booth 4U9). The patrol frigate could be built at the company's Ingalls Shipbuilding facility in Mississippi.

"The National Security Cutter is a ship with tremendous capability and a demonstrated operational performance at sea," said Mike Duthu, Ingalls Shipbuilding's Coast Guard program manager. "There is a large market for patrol frigates internationally. By combining a stable design baseline with an experienced workforce and active construction line, we have developed a product that could meet the mission needs of several foreign navies."

Ingalls Shipbuilding has delivered three National Security Cutters to the Coast Guard, and two more ships are currently under construction. The Coast Guard plans to purchase a total of at least eight NSCs.

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 418 feet long with a 54-foot 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.

Both frigates retain the NSC's propulsion system of one LM2500 gas turbine and two MTU20V 1163 diesels in combined diesel and gas configuration. All variants incorporate the current quality-of-life features on the NSC, including modern berthing compartments, entertainment facilities and workout facilities.

HII representatives Capt. Rocco Tomanelli (U.S. Navy, Ret.) and Capt. Patrick Stadt (U.S. Coast Guard, Ret.), who was the first commanding officer on the National Security Cutter Bertholf, will display NSC and patrol frigate models at booth 4U9 in the U.S. Pavilion throughout the show.

Ingalls Shipbuilding Sea Control Frigate

Published on Apr 14, 2014

Based on Ingalls Shipbuilding's proven National Security Cutter hull, the capability mix on this ship class aligns to the needs of several of the world's navies. Among the features are an extensive flight deck and hangar facility, proven propulsion train, outstanding habitability features and extended range and endurance.

Christie Thomas (Director of Business Development at Ingalls Shipbuilding) presents the Patrol Frigate design.

It is based on the company's proven U.S. Coast Guard National Security Cutter (Legend class NSC). The company's patrol frigate consists in several militarized version of the NSC with increased lethality and upgraded combat systems but retaining the same hull form.

What appears to be a follow on design:

Document also calls for new frigate and patrol craft.
"
In the proposed architecture, the LCS/FF program would be truncated as soon as the design of a new FFG is ready to build. This would ideally be in FY19, but may be FY20 or FY21. The 4000- to 5000-ton FFG would be designed with the endurance to accompany the Maneuver Force or for convoy escort; an active and passive EW suite; an ASW suite including a VDS sonar and passive towed array; and a 16- to 32-cell VLS magazine with ESSM for medium- range area air defense, long-range surface-to-surface missiles, and a stando ASW weapon capable of quickly putting a submarine on the defensive more than 50 nm away.
"

Sounds a lot like the Legend-class National Security Cutter-based Patrol Frigate 4921 concept.
