The Firefly combined rugged construction with reconnaissance, rocket strike, air-defense, and anti-submarine potential. Its adaptability gave the aircraft a longer and broader career than a narrowly optimized design might have achieved.

That change should not be read simply as evidence that Britain had been unable to develop its own equipment during the war. It fits within the economic and supply shock caused when Lend-Lease ended immediately rather than gradually, disrupting British plans and American units that also depended on exchanged equipment.
