Project 69 was designed for 32 knots and six 15-inch guns, but its specifications lead directly to a logistics problem. Multiple gun calibres and technically ambitious solutions create separate ammunition and support burdens. The Royal Navy faced a similar mixture of 14-inch, 15-inch, 5.25-inch, 4.7-inch, 4.5-inch, and 4-inch weapons before the Second World War. Every calibre could answer a design requirement while making the fleet as a whole harder to sustain. Standardisation is a force-design choice with operational consequences.

Project 69 and the logistics behind a big-gun fleet
Project 69 shows how impressive speed and armament could create ammunition and support burdens across a growing fleet.
