Always the same boat

[Roger Dodger]

I've noticed that I always seem to draw the USS Drum when I get a Gato-class boat, and always get the USS Balao when I get one of that class. Only once did I get the Gato. So far, I've never started my career with either a Gato-class or Balao-class boat. Usually I start out with an S-Boat in the Asiatic Theater, and work my way up from there when I 'earn' a new boat. So, I rarely get a Gato-class sub until around mid-42, sometimes later. The Balao-Class boats are not available until after 1 Jan, 43.

I've looked through data\roster\american\submarine\boatclass.cfg and found:

Gato-Class: there are UNITS 1 through 10, all with a DOC on or before 19411231. 73 total UNITS. The USS Drum is UNIT 1

Balao-Class: there are UNITS 1 through 7 with a DOC of 19430101. 116 total UNITS (some with a DOC at the end of the war, even later). The USS Balao is UNIT 1.

Isn't the program supposed to select your boat randomly (subject to dates of availability), or does it just pick UNIT 1 'most' of the time?

Can the order of the UNITs be changed before starting a career? Like exchange any of the other 9 available boats (Gato) in the UNIT 1 position?

Inquiring minds want to know.
