Cummins and Fischer Panda have decades of military gensets fielded. The differentiators left are the naval dual-frequency set and who holds the export gate.
Cummins builds the US Army's AMMPS line and Fischer Panda has thirty years of defence power behind it. Both publish real, qualified sets. Our case sits at the two ends they leave open: a 2 kW to 800 kW band that reaches further than either published range, a national navy's 400/500 kW dual-frequency container set, and supply from an independent maker with no major-power political strings.
Our generating sets are proven in service with a national army, navy and air force, not on a test pad. The naval dual-frequency sets were field-tested with a national navy, and the group is the sole technically and commercially qualified vendor on that programme. Every transfer is governed by classification and end-use controls.

What the table means
The incumbents own the mid tactical band, and they publish it well
Cummins builds the US Army's AMMPS at 5, 10, 15, 30 and 60 kW in 60 Hz and 400 Hz, states a full line to 2.5 MW, and publishes an RMP set at 60 kW that runs 50, 60 and 400 Hz in one box to MIL-DTL-32496 and MIL-STD-461F, with power quality and a 72 dB(A) noise figure on the sheet. Fischer Panda has thirty years of fielded defence gensets, a DC range from about 2 kW, an AC range to 25 kW, dedicated 400 Hz air-defence sets and a 57 dBA SST-10. If a buyer wants published tactical mid-power sets to point at, both catalogues exist and they are credible.
The band ends and the naval set are where our case is strongest
Our published band runs 2 kW to 800 kW as a single supplier relationship. Fischer Panda's individual defence models top out around 25 kW and scale by paralleling; Cummins names sets to 60 kW with a full-line claim to 2.5 MW that would be a different product family than the fielded AMMPS. At the top of the band sits the differentiator neither incumbent publishes in the reviewed documents: 400 kW and 500 kW dual-frequency ISO-container naval sets, field-tested with a national navy, on which our group is the sole technically and commercially qualified vendor. A ship's power is a 50/60 Hz problem, and a switchable container set answers it directly.
Where the incumbents publish more, we say so
Cummins and Fischer Panda both publish fuel-compatibility lists, per-model weights and numbered noise levels. On the site today we do not publish a per-set fuel list, a per-model weight, a paralleling capability or a numbered dB figure, and pretending otherwise would be worthless. Those go on the request list. What we do publish is the qualification spine, JSS 55555, JSS 6115, CQAL 640A/B, MIL-STD-461, MIL-STD-705 and DEFSTAN 08-142 on naval work, plus a written line-by-line compliance matrix against the customer's own standard rather than a claim to a foreign default.
The genset carries its politics into year six
AMMPS is a US program of record, so its export follows the US regime and its priorities. Fischer Panda carries the EU regime. Neither shows up in a power-quality table, and both show up when a customer wants to move sets to a border, run them through a diplomatic change, or keep spares flowing for a decade. Our sets come from an independent maker through a non-aligned channel, sustained in region by one accountable team. For a ministry that has watched capability frozen by a supplier's foreign policy, that is the decisive line, not the dB figure.
Questions buyers ask
What is the best alternative to Cummins AMMPS for a buyer who cannot accept US export conditions?
AMMPS is a mature, heavily fielded line: 5 to 60 kW in 60 Hz and 400 Hz, MIL-STD-461, multi-fuel on JP-8 and diesel, and more than 25,000 units delivered to the US DoD. But it is a US program of record, so its export and support follow the US regime. If that is the obstacle rather than the engineering, our generating sets cover the same tactical band and reach further, 2 kW to 800 kW, qualified against JSS 55555, MIL-STD-461 and MIL-STD-705, from an independent maker sustained in region with no major-power approval gate. Compare on the qualification matrix first, then on what each supplier can promise about year six.
Which military generator manufacturer offers a naval dual-frequency set?
In the documents we reviewed, neither Cummins nor Fischer Panda publishes a 400 to 500 kW ISO-containerised dual-frequency naval set. Cummins' RMP is tri-frequency 50/60/400 Hz but at 60 kW and land-tactical in focus; Fischer Panda publishes marine and 400 Hz air-defence power but as separate models. Our line publishes 400 kW and 500 kW dual-frequency 50/60 Hz container sets, field-tested with a national navy, where our group is the sole qualified vendor on the programme. If your requirement is ship or shore power that must switch cleanly between 50 and 60 Hz at that rating, that is the specific gap our set fills.
How wide is the power range of a military generator set, and does range matter?
On published figures, our band of 2 kW to 800 kW is the widest single-supplier range here. Fischer Panda's individual defence sets run from about 2 kW to 25 kW and scale by paralleling; Cummins publishes named AMMPS and RMP sets to 60 kW with a full-line claim to 2.5 MW. Range matters when one force needs a two-man-portable tactical set and a containerised installation from the same accountable supplier, which cuts the number of training pipelines and spares chains. If you need one power point, the narrower ranges are fine and the decision moves to noise, weight and supply terms.
What military standards must a defence generator meet?
The spine is EMI control, power quality and environmental durability. Cummins publishes MIL-STD-461F for EMI, MIL-STD-2169 for RF emissions and MIL-DTL-32496 with numbered power-quality tolerances on the RMP. Our sets publish JSS 55555, JSS 6115, CQAL 640A/B, MIL-STD-461 EMI/EMC, MIL-STD-705 power quality, and DEFSTAN 08-142 with EED-Q-242 on naval programmes. Fischer Panda states MIL-STD-461 and MIL-STD-810 without a numbered power-quality standard in the documents we read. When two sets both claim MIL-STD-461, ask which revision and which sub-tests, and ask for the written compliance matrix.
How quiet is a military generator, and which is quietest?
Noise is a survivability issue near the front. Fischer Panda publishes the lowest figure we found, 57 dBA at 23 feet for the SST-10; Cummins publishes 72 dB(A) at full load at 7 m for the 60 kW RMP, with variable-speed fans to manage it. We state low noise as a design goal but do not publish a numbered dB level on the site today, so treat it as a written question. Remember that quieter sets are usually smaller, so compare noise at a stated distance and load, and against the power you actually need.
Can military generator sets be paralleled into a microgrid?
Cummins publishes the strongest answer: the RMP Advanced Digital Control System forms a microgrid of paralleled sets with no external control devices and two-button automatic synchronisation. Fischer Panda offers parallel, scalable power systems to build higher aggregate output from multiple sets. We do not publish a paralleling or microgrid capability on the site today, so if aggregation and redundancy across multiple sets is a hard requirement, put it in writing and ask for the control-system detail rather than assuming it either way.
Which is better for a containerised installation, a tactical genset or a large fixed set?
It depends on the load. For a mobile command post or a light-forces node, the tactical sets from Cummins and Fischer Panda, in the 5 to 60 kW band, are purpose-built and air-transportable. For radar, a launcher farm or naval and airfield installations, the answer moves up the band to skid, trailer and ISO-container builds, where our line runs to 800 kW and includes the 400/500 kW dual-frequency naval container set. Size the set to the real load with a load study first, because an oversized set idling at low load wastes fuel and an undersized one browns out the radar.
