Will the Government Accept one L5-30R (locking) for

PDU's to distribute more 120V receptacles

No, UPS must have several output locking receptacles for simplicity of equipment integration and lessening failure points.

Technical

Specifications the requested 30 AMP 120V input to provide 1.5kVA is not doable. At minimum, off of a L5-30P, it will be at 3000VA.

Will the Government accept L5-20P/5-20P (or even a standard 5-15P), then we can likely size down appropriately

Lowering the AMP for a suitable UPS (1.5KVA having L5-

20/15P) is acceptable.

Output Connection: (4) NEMA 5-30R – the maximum current is 8.2Amps Are NEMA 5-15R Outputs acceptable?

Yes, NEMA L5-15R outputs are acceptable.

Specifications 2.1.2.1

System Capacity: 3.0kVA / 2.25kW: The system capacity is outside of the allowed value for

Reference i. MIL-DTL-24765B which has a maximum capacity of 3.0kVA / 2.1kW.

Please clarify the correct capacity.

The Government reviewed MIL-DTL-24765B and could not find the noted requirement for maximum capacity of

3.0kVA/2.1kW. It is acceptable to move forward with maximum capacity of 3.0kVA / 2.1kW, if necessary.
