                      The Me262A-1a/U1

The Me 262A-1a/U1 was a test version of the Me 262 that had,
as an alternative weapons suite:
2 x MG 151 20mm cannon with 146 rounds per gun.
2 x MK 108 30mm cannon with 66 rounds per gun.
2 x MK 103 30mm cannon with 72 rounds per guns.
The installation of the MK 103 cannon dictated a bulged
fairing on each side of the nose, and only three examples of
this configuration were built.
