Swedish subs

I believe these are first class submarines of the 'Draken' Class
Coincidentally there were three in this class of sub named 'draken' 'Gripen' and 'Ulven' I believe they are all seen here in this picture.
note the letters on the Conning towers

Just discovered that ' Ulven' was lost in a German minefield 16/4/1943
