SAS 2017: Austal Unveils Updated LCS Frigate Design with 16x Anti-Ship Missiles
 
At the Navy League’s Sea-Air-Space 2017 exposition currently held near Washington D.C., Austal USA rolled out an updated LCS Frigate design called the "Austal Frigate". The main modifications consist in a slightly shortened flight deck in order to fit anti-ship missile launchers and a variable depth sonar in order to add capabilities to the ship's aft.
     
The new Austal Frigate features a redesigned stern to add capabilities to the ship's aft.
     
According to Austal USA, the Austal Frigate possesses increased lethality and high-speed shallow draft multi-mission combatant capabilities on a seaframe nearly identical to the Independence-class Littoral Combat Ship. This ship's ability to meet and exceed current US Navy requirements makes it one of the most cost-effective, maneuverable and flexible ships in the fleet.
     
The new Austal Frigate features a redesigned stern to add capabilities to the ship's aft.
     
Thanks to the extra space at the stern, there are now 8x over the horizon (OTH) anti-ship missiles in additition to the 8x launchers fitted forward, for a total of 16x anti-ship missiles. An Austal representative explained to Navy Recognition that the increased number of missiles exceeds the minimum requirement expressed by the US Navy, but is in line with the distributed lethality concept and doesn't need additional development.

The new stern space is also fitted with a variable depth sonar and its handling system as well as a towed array.

The new Austal Frigate design features optional Mk41 VLS (16 cells) in addition to the SeaRAM launcher.

Austal insists on the fact that the seaframe from the maindeck down is virtually identical to the existing LCS design and retains its qualities in terms of performance and affordability.
