ORIGINAL: el cid again
For upgrading I beg to differ. The Editor Manual clearly states that a device cannot upgrade till the date in which the new device is available (page 8). If this is not the case then the biggest BUG that has gone unnnoticed till now has appeared. So I just set the date for the 90mm to be available in 4203 and the 40mm in 0644. BTW, this will also mean a seperate 40mm for the US from the British which have theirs available since 1940.
Your understanding is correct. Somehow you misunderstood what I said, which is the same thing. I didn't catch the reason for a different US 40mm though - it may be a problem for me. I have integrated devices where ever possible to create free slots. Hmmm.
Quite simple. The British had used it since at least 1940. The 40mm in the devices is this one.
According to the US Army Ordnance Greenbooks
(Vol 2:78)
"After the two pilot guns were shipped to Aberdeen for test in July 1941, both Firestone and Chrysler began tooling up and were ready for quantity production soon after the Japanese attacked Pearl Harbor. But by the end of the year no 40-mm. guns had been completed."
(Vol 2:85)
"The 40-mm. was in the hands of two strong producers, Chrysler and the Pontiac Division of General Motors, but Chrysler was just starting production in February 1942 and Pontiac,
with a priority of A-1-d, found it could not get essential tools."
Chrysler was only able to get started by February. An informed guess would be around June before the Pacific seen any, considering that the European war had priority. Instead the 37mm was disgnated the acceptable subsititue.
(Vol 2:86)
"...the higher authorities approved, that the 37-mm. gun be accepted as a substitute to make up the deficit in 40-mm. output."
The US Army could not historically have 40mm guns until at least March 42, then in limited numbers. It was not unitl the end of 1943 that 40mm production was greater than the 37mm.
As a friend says "You cannot get there from here"
To make empty slots I have moved the large CD guns to slots higher than 535. I know that they still show up in the units and seem to get produced. Have not tested whether they are funtional though, although they should be...
