The proposed destroyer is large enough for three twin 4.5-inch BD mountings, ten torpedo tubes, and later additions of medium and light anti-aircraft weapons. Greater stability and reserve space would make the design easier to adapt than the smaller historical L and M classes. Available yard capacity might also have supported twenty-four rather than sixteen ships, while Henderson's success in protecting HMS Unicorn shows how a politically skilful sponsor could secure an unconventional programme. Unicorn's design work later fed the light-fleet carrier programme, showing how preserving a single experimental ship could generate a broader wartime design family.

A large L class could anticipate the Battle-class destroyer
The larger L-class hull offered room for dual-purpose 4.5-inch guns, torpedoes, and wartime anti-aircraft growth in a design entering service years before the Battle class.
