Babcock offers 6,000-ton Arrowhead 140 frigates to US Navy

London-based Babcock has offered its Arrowhead 140 frigates to the U.S. Navy. The 138-metre, 5,700–6,000-ton vessels exceed 28 knots and underpin Britain's five-ship Type 31 programme, with Poland and Indonesia also selecting the design. Babcock lacks a U.S. shipyard, making an American partner such as Huntington Ingalls Industries central to the proposal.

• Frigate is 138 m long and displaces 5,700–6,000 tons
• Speed exceeds 28 knots on a diesel-and-diesel propulsion system
• Design forms the basis of Britain's five-ship Type 31 programme
• Babcock needs a U.S. partner, likely Huntington Ingalls Industries
