Uboat front clasp

[Avatar]

Lots of good info here. But currently at the top commander's screen, I have 200.(something) tons(58% realism). Since I've only awarded medals through the SH3 Commander Manage crew screen, I think I may have missed the opportunity, by not updating the awards at the main career page(the office) during post patrol.
I now check the awards offered post patrol to see if the front clasp will appear, but if historical inaccuracy will not let me do this until 1944, then there is no problem.
I was just afraid that I missed the opportunity to award the crew with the Uboat Front clasp.
I'm probably way off, historically speaking, when it comes to my crew with ranks and medals anyway, so no harm no foul.

I almost forgot, when the opportunity came to award the crew with the first uboat badge(in the awards page of SH3), SH3 Cmdr warned me of a historical inaccuracy, but I was able to give them out anyway. This is what led me to believe that I could give out the front clasp in the first place.
again thanks for the info

EDIT: my character, the uboat commander, already has the front clasp and its fall 1940.
