What assurances can the Minister give that in attempting to develop a common requirement for a new air defence frigate we shall not end up with another fiasco of expensive and fruitless bickering between countries with different design requirements? The NFR90 project suffered difficulties of that kind and our involvement in it led to almost two years being wasted. Can the Minister tell us whether Britain's shipyards will be assured of a very early decision on a type 42 replacement, thus allowing for some continuity of work and ending the grave uncertainty in the shipyards so that men and management can get on with what they do best—building ships in British yards?
