Curious Craft from Austal

Mobile, Alabama-based Austal USA, builder of the Navy’s Spearhead-class Expeditionary Fast Transport (EPF)– which have gotten good reviews– and the Independence-class littoral combat ship– you know, the class of LCS that kinda-sorta works– released these interesting artist depictions of future designs without much context or details.

The company was recently given a $44 million contract from the Navy to develop one of its EPFs as an autonomous surface vessel, so keep that in mind.

This appears to be a larger version of the EPF with a huge 96-cell VLS section, a concept that could be a budget arsenal ship. A Tomahawk raft, if you will. The Spearheads use 40~ man crews. 

Speaking of arsenal ships, this looks to be a larger version of the company’s 58m OPV, stretched to add a long (strike length?) 32-cell VLS section. Note the Large Unmanned Surface Vehicle (LUSV) designator on the hull and the airborne sensor off the stern. Besides the VLS, the only other armament visible is four M2 .50 cal mounts. The small number of liferafts hint at accommodations for a tiny transit or combat crew. 

Odds are, this is an autonomous design for ISR purposes

Look at this sweet trimaran. Envision a 53-foot container that can hold anything from ASMs to IRBMs or a mine-hunting det, which would make sense if the design incorporates a composite hull. An MCM LSUV, if you will. 

Huntington Ingalls Wants to Make a LPD Arsenal Ship to Knock out Ballistic Missiles

Using the basic LPD 17 hull designed for the U.S. Navy’s San Antonio-class amphibious transport dock ships — all of which are built by HII — the BMD ship incorporates an Aegis-type phased array radar atop the superstructure. The aft deck, devoid of much of the topside structure of the LPD 17, is ringed by 18 16-cell vertical launch system launchers, for a total of 288 missile cells.

Like the existing Mark 41 and Mark 57 VLS launchers in the fleet, the ship’s VLS would presumably be able to launch a variety of weapons, including SM-2, SM-3 and SM-6 Standard missiles, Tomahawk cruise missiles, and other weapons. Forward on the ship, HII placed a fairly large rail gun mount, a system now under development by the Navy. The model features 57mm guns in mounts similar to those on the Littoral Combat Ships and Coast Guard National Security Cutters, but not the Mk 46 30mm mounts fitted to LPD 17s.
