John Howie, the chief executive of Babcock International's marine business on Royal Navy's Type 31 Decision, Capabilities, Affordability in interview with Vago Muradian of Defense & Aerospace Report. Quite informative. Of note at 14:09 during the interview he states that they are expecting most of the exports to be sales of the design, systems and engineering expertise, rather than actual ships, because most customers will want the ships built in their own yards.
