A follow on from the Tyr class, 2 ships planned, Thor and Aegir

Secondaries are twins, simmed as triples to assertain extra weight of HA/LA mount, weight then added as misc weight, in this case 73 tons.

4 Aircraft to be carried, type yet to be decided upon, with catapult

Torpedo bulkhead is a twin layer arrangement, the outer layer being 20mm thick, the inner 30mm.
