1:600 Crossbow, Scorpion was similar. Note forward 4" AA, funnel arrangement, bulky STAAG turrets aft and squid housing on aft end of aft shelter. The mortars fired one on each beam, the forward one to starboard and the port to aft © Andrew Arthur

1:600 Broadsword. She and Battleaxe differed in the transposing of "B" 4" gun and squids and in shipping an STD director aft of the fore-funnel to cover the rear arcs of fire. Crew was also slightly increased © Andrew Arthur

Despite being an excellent and sound design, compared tho the 'utility' classes, it's hull was too big to fit into the smaller yards for building, and a smaller desing was drafted, on the "Z" class hull, but because a full AA armament was requested, they had to break the change to 4.5" guns and revert to the 4" to allow sufficient numbers to be carried. ( despite the fact it had been repeatedly rejected as too light for fleet work throughout the war.)
A surprising innovatio, for a British destroyer, was the unit machinery arrangement, and the isolated boilerd required seperate funnels, and the unnatractive rig of the "D" class was used; a large exhaust trunked up through the lattice and an isolated stump funnel aft - not very nice on the eye.
The designed AA armament was a new twin 4" AA turret in "A", "B" and "X" positions, two RDF fitted director controled twin 40mm's sided on the fore end of the aft shelter deck, two twin 20mm's in the wings and two quadruple 21" torpedoes.
Cessation of hostilities resulted in 15 units being cancelled, and the survivors had a modified armament;
Two squid mortars replaced either "B" ( Battleaxe and Broadsword ) or "X" ( Scorpion and Crossbow ) guns, in a large housing, the twin 20mm's were replaced by single 40mm Bofors, and the STD tower controlled Bofors twins were replaced by RDF fitted "STAAG" twins. Quintuple torpedoes supllanted the quads, and the depth charges planned were redced to a mere 15.
RDF comprised of GW type 293 on the lattice foremast, AW type 291 on the pole mainmast, GR type 275 on the Mk.VI HA/LA DCT, AR type 262 on the STAAG Bofors, and where the 4" guns were fitted in "A" and "X" positions, a barrage director fitted with AR type 282 was carried behind the fore-funnel to give direction in this arc of fire.
