|Desired characteristics of the LMG11 were as follows: |
Firing must be possible in all static and dynamic firing conditions.
Effective fire from ranges of 0-600 m.
Overall LMG weight without ammunition must be less than 5 kg.
Throw away type magazine desired, capacity 200 rounds.
Capable of long suppressive fire
No cook-off after firing a full magazine
Operable by mounted and dismounted infantry
Easy to handle, rapid to engage in all kinds of terrain
High significance for firing on the move
Sufficient firepower for suppressive fire
High ammunition capacity, no need for reloading during longer combat sequences
Same caliber as the G11 rifle, 4.73 x 33 caseless.
What HK actually produced, based on the above desired characteristics:
Total weight, including 300 rounds: Less than 7 kg
Magazine capacity: 300 rounds
Disposable compact magazine, waterproof, reloadable, no magazine spring
Overall weapon length: less than 900 mm
Revolver breech drum with three chambers (no cook off after 300 rounds sustained fire!)
Recoil operated breech system
Rearward floating system
Rate of fire: Less than 600 rounds/min
It is not known to what extent this G11 sub-project was developed. The first photograph appears to be an actual weapon, rather than a line drawing, so I am led to believe that at least prototypes were assembled, and the above data appears to indicate firing models existed and were tested.
