Recent emphasis has been laid in German communiques and in official evaluation of
them, on the high degree of cooperation between the Luftwaffe and the submarine
arm, especially in action against convoys heavily armed. According to the
German technical press, among the many new submarine commanders and officers
who have been acquiring the war buckle of this service are those who have
previously carried pilot wings and have earned air-service decorations on the front.
The only explanation given for transferring air-service personnel to submarine duty
is that the valuable experience such officers have acquired in air command posts has
aided in producing the excellent results being achieved by the submarines.
The possibility also arises, however, that physical disabilities which disqualify
an officer for active flight duty in the Luftwaffe may not render him unfit
for service aboard a submarine.
