Three types of warhead of equal weight, 500 kilograms, were projected for the E-4. The type which seemed to have accrued the most favor among the Messerschmitt engineers and the local flak officers was built up of a metal shell or container 1 1/2mm thick. The shell was lined with cylindrical pellets cast of mild steel 20 by 30mm containing an incendiary core! The explosive cast into the resulting cavity contained a booster charge and fuze in it's forward end on the longitudinal axis.

   Tests of the above type warhead showed that it could be expected to put 1.5 pellets in an area of 1 square meter at a range of 65 meters.

   The second type of warhead incorporated 550 small rockets driven by gunpowder which have been developed by one of the SS laboratories and were to be used as part of the armament of the Me 262. The rockets were mounted in the warhead to fire in a 30 degree cone from a maximum range of 300 meters; their effective range, however, was 550 meters and at that range each rocket was considered capable of destroying a bomber.

   The third type of warhead was straight explosive dependant only on concussion to destroy the target.

   Both proximity and self-destruction fuzes were provided. The proximity fuzes were projected on the I.R., Electronic, and acoustic principals; however, the latter had essentially been dropped by the designers as the maximum range at which the actuating impulse was of sufficient magnitude was too small to derive most effective results from the warhead.
