RNAS YEOVILTON, U.K. — Lockheed Martin is to offer a U.K-specific variant of its SC-130J Sea Hercules to Britain, as the U.K. looks to re-generate a maritime patrol capability. The company says it could convert the U.K. Royal Air Force’s existing fleet of C-130J airlifters into SC-130Js, reducing procurement costs and technical risks, company officials told Aviation Week on the eve of the RNAS Yeovilton Air Day.
