Project history: Since the 1931 program destroyers have ceased to be shared on equipped mainly minesweeping or anti-submarine armaments: "Å" class destroyers carried both. Moreover, it was supposed to equip these ships also with the minelaying equipment. It was originally planed to equip in a similar way all destroyers but absence of operating experience of a new minelaying drive had to be limited to two suppressors Esk and Express.
The extended armament structure conducted to growth of displacement and as consequence fall of speed. To avoid it new destroyers had improved hull form that managed to be reached after very many model tests in a ship-research bassin.
The important difference of "Å" class from previous "C" and "D" classes was the sectioning of 2nd boiler room by a watertight bulkhead on two smaller. Thus, boiler rooms became 3 as figure of boilers that has positively affected damage tolerance.
76mm AA gun figuring in the project at early phases was cancelled in favour of new main gun mounts with an 40° elevation angle. New Mk XVII mounts ensured more elevation angle at the expense of rather original reception. There was a ring in a deck round a mount more than 2m in diametere and 35cm deep. It was covered by special metallic boards at surface fire. These boards were lifted at big elevation angles, that ensured standard gun recoil with natural balancing, removing risk of blow of breech in a deck. This construction has called subsequently a number of critical remarks because of the impracticality however used on destroyers of three classes up to "G".
"F" class (1932 program) became repetition of "Å" without any changes in the design. The order for their building has been given out simultaneously with destroyers of 1931 program.
