Admiral Fisher had always objected to heavy secondary batteries on capital ships, so at his insistence, the 4" (10.2 cm) caliber was chosen for the secondary weapons on the battlecruisers of the Repulse and Courageous classes. Initially, either the 4" (10.2 cm) QF Mark V or the 4" (10.2 cm) BL Mark VIII were to have been installed, but the first weapon was difficult to arrange for director firing and the second had a low rate of fire. The best features of both, the Mark V body and the Mark VIII breech mechanism, were combined to create the Mark IX.

The Repulse class battlecruisers used both single and triple mountings, with the latter mounting having the guns individually sleeved, an unusual feature for a secondary weapon. This mounting required a very large crew of 32 and, as it lacked power assist, proved to be quite cumbersome.

During World War II, this weapon was used in single mountings on many corvettes as well as on numerous smaller ships including 1,200 on DEMS.

Mark IX was of wire wound construction with tapered inner A tube and jacket. Mark IX* differed in having no inner A tube. Mark IX** was introduced to suit older manufacturing equipment at EOC and COW and had no inner A tube, a B tube and overlapping short jacket and an old-style step wire-winding method. All had Welin breech blocks with Vickers mechanisms. Some 2,382 were built of which 2,193 were still in service as of September 1939. Actual bore length was 44.35 calibers.
