The battleships would have been equipped with lattice towers that would hold searchlight platforms.

The Japanese aircraft, using clouds as cover, dove and released three bombs against Colhoun, two splashing nearby and one striking the after searchlight platform and a nearby boat.

One pair of these was added to the bridge wings and the other pair was mounted on the searchlight platform.

The other guns were carried one between the first and second funnels, one after the searchlight platform and one on a bandstand on the quarterdeck.

The ineffective 0.5 inch machine guns were replaced with single 20 mm Oerlikon guns, and another pair were added on the searchlight platform, amidships.

While negotiations were in progress Frick had a tall fence built around the mill and erected searchlight platforms in the mill yard - hardly a peaceful gesture.

Torpedo mounts No. 2 and No. 3 were moved closer together and the searchlight platform formerly between them was moved forward to just aft of the second funnel.

I added for the 4 in guns, which was fitted amidships between the searchlight platform and the after funnel.

The funnels were modified with raked caps and searchlight platforms on their sides.

Armament was increased over the Acastas, with the number of torpedo tubes doubled to two pairs - abaft the funnels - with a small searchlight platform in between.
