I started a career in an S Class boat out of Cavite/Manila, migrated as usual through Surabaya to Perth-Fremantle, received an upgrade, and then had the base change to Brisbane. My Sargo class boat still had a .50 Cal AA and a 3.5" deck gun. In early 1943 I was upgraded to the Balao. I have all the expected equipment, except that it has two .50 Cal AA guns and still have the 3.5" deck gun.
In all previous versions of careers I was always able to upgrade to at least the single 20mm AA gun and the 4.5" deck gun, usually even before getting the surface radar, but not this time. Neither is offered. This is the only career in which I was sent from Fremantle to Brisbane.
Is it because I am still in Brisbane?
Boat History:
USS S-23 (SS-128), starting from Manila 12/08/41 - Completed 4 Patrols, with base changes to Surabaya, then Perth-Fremantle, then Brisbane - no transfers requested.
USS Sturgeon (SS-187), starting from Brisbane, 9/2/42 - Completed 3 Patrols
USS Saury (SS-189), starting from Brisbane, 2/21/42 - Completed 3 Patrols
USS Balao (SS-285), starting from Brisbane, 7/11/43 - Completed 2 Patrols (so far)
No armament changes since 12/8/41 on any boat. Seems very strange.
