Military diesel generator sets

What is a military diesel generator set?

It is a generating set built for survivability rather than utility uptime, because on a defence platform it is the single point on which a radar sweeps, a launcher cycles and a command post stays on the net. Ours cover 2 kW to 800 kW, from two-man-portable tactical units to ISO-containerised naval sets, and are qualified against JSS 55555, MIL-STD-461 for EMI control and MIL-STD-705 for power quality. They are proven in service with a national army, navy and air force, and they are available for export.

See: Defence-qualified generating sets

Military generator set price

We do not publish a price, because the number moves with the rating, the build type, the standard set you specify and the EMI containment your equipment needs. Treat any figure you are shown as a quotation against your load, not a list price. What we can settle early is the band, 2 kW to 800 kW, the build options from portable to ISO-containerised, and the qualification set, so a briefing fixes the technical fit before commercial terms come into it. We also run a load study before recommending a rating.

Military vs commercial diesel generator

The difference is what the standards buy you. A commercial set is specified for uptime; a defence set is specified to keep working when the environment and the electromagnetic threat are against it. Ours are qualified against JSS 55555, JSS 6115, CQAL 640A and B, MIL-STD-461 for EMI and EMC and MIL-STD-705 for power quality, with the EMI containment engineered into the canopy itself. They are proven by test to operate to minus 30 C, store to minus 40 C and run at altitude to 5,000 m, through rain, dust, salt-fog and cold-start.

EMI-quiet generator for a radar and comms installation

This is where the canopy earns its place. EMI containment is engineered into the set itself, with hot zinc-sprayed mating surfaces, conductive gasketing, honeycomb vent filters, conductive glazing and filtered power circuits, so the set can sit close to a radar or a command post without corrupting the receivers it powers. The compliance backing it is MIL-STD-461 for EMI and EMC and MIL-STD-705 for power quality, alongside JSS 55555. Radar, launcher and missile systems and command posts are among the published applications, so the quiet build is the norm here, not an option.

See: EMI containment and applications

How do you size a generator set for a forward operating base?

With a load study, not a guess. The selection support runs to a load study, a rating recommendation and a written compliance matrix line by line against your own standard, so the rating follows the actual demand of your radar, comms, launcher and base loads. The band available is wide, 2 kW to 800 kW across portable, skid, trolley, trailer and ISO-containerised builds, which means the recommendation can land on the right rating rather than the nearest one. Forward operating bases are a published application, so bring your load list to a briefing.

Dual-frequency generator set for a naval programme

There are 400 kW and 500 kW dual-frequency sets running at 50 and 60 Hz, built ISO-containerised, and they have been field-tested with a national navy. On that programme The Defence Power Group is the sole technically and commercially qualified vendor. That combination, dual-frequency output in a containerised naval build with test evidence behind it, is unusual, and it is one of the published applications alongside radar, launcher and missile systems and airfield installations. We can walk the compliance detail against your naval specification, including DEFSTAN 08-142 and EED-Q-242 where they apply.

See: Dual-frequency naval sets, Where the naval dual-frequency set sits against the field

Generator qualified for cold-start in the mountains

Cold and altitude are proven by test here rather than assumed. The sets are qualified to operate to minus 30 C, store to minus 40 C and run at altitude to 5,000 m, and cold-start is a tested condition alongside rain, dust and salt-fog. That matters because a set that starts on the bench at room temperature is a different machine from one that starts on a mountain at dawn. Give us the ceiling, the minimum temperature and the start requirement for your site and we confirm the build and the test evidence against it.

See: Environmental qualification by test

Can these generator sets run in parallel and switch over automatically?

Parallel and auto-changeover options are published on the 40 kVA to 125 kVA class, which is the systems and airbase band aimed at critical communication and radar loads. That is the extent of what we state on the site, so we will not claim parallel behaviour across the whole 2 kW to 800 kW range where we have not published it. If your requirement sits in that 40 kVA to 125 kVA band, the changeover and parallel options are there; if it sits elsewhere, ask us to confirm what is available against your rating in a briefing.

See: Systems and airbase class

What qualification evidence backs the claim that these sets survive salt-fog, dust and cold-start?

The environmental envelope is proven by test, not asserted: operation to minus 30 C, storage to minus 40 C, altitude to 5,000 m, and rain, dust, salt-fog and cold-start all qualified by test. On the electromagnetic side the sets meet MIL-STD-461 for EMI and EMC and MIL-STD-705 for power quality, with naval programmes adding DEFSTAN 08-142 and EED-Q-242. The 400 kW and 500 kW dual-frequency naval sets have been field-tested with a national navy. We can present that evidence against your own specification as a written compliance matrix, line by line.

See: Environmental proof and compliance, Request a capability brief

We need clean, EMI-controlled power for a radar site. What proves the set will not corrupt the receivers?

The containment is built into the canopy rather than bolted on: hot zinc-sprayed mating surfaces, conductive gasketing, honeycomb vent filters, conductive glazing and filtered power circuits, all backed by MIL-STD-461 for EMI and EMC and MIL-STD-705 for power quality. Radar is a published application, and the systems and airbase class in the 40 kVA to 125 kVA band is aimed specifically at critical communication and radar loads with a clean waveform. The proof you should insist on is a written compliance matrix against your standard plus the test data, both of which we can provide.

Can we procure ISO-containerised naval generating sets without a major-power supplier's political conditions?

The sets come from an independent, non-aligned source, so there is no major-power supplier's political strings travelling behind the sale, and the 400 kW and 500 kW dual-frequency containerised naval sets have been field-tested with a national navy. That said, any transfer is subject to export controls and end-use approvals, and localisation arrangements are scoped per programme rather than promised outright. We will not tell you the capability comes free of conditions, because no real naval sale does. The honest position is independent origin with the export and end-use terms stated up front.

See: Independent origin and naval sets, Supply conditions set against Cummins and Fischer Panda, How Unstrat structures a national requirement

How do you build a written compliance case against our own national generator standard?

By working from your standard, not ours. The selection support starts with a load study and a rating recommendation, then confirms the environmental envelope and produces a written compliance matrix line by line against your specification. Because the sets are already qualified against JSS 55555, JSS 6115, CQAL 640A and B, MIL-STD-461 and MIL-STD-705, with DEFSTAN 08-142 and EED-Q-242 on naval programmes, most national standards map onto an existing evidence base rather than a new campaign. Send us the standard and the load list and we build the matrix around them in a briefing.

See: Selection support and compliance matrix, How an engagement is structured

Who sustains a mixed fleet of tactical, airbase and containerised sets once they are in service?

Sustainment is held in region with one accountable team, so a fleet that spans two-man-portable tactical sets, the 40 kVA to 125 kVA airbase class and 400 kW containerised naval sets is supported through a single channel rather than several. That matters more over a decade than any datasheet line, because the cost that bites is the set that fails on a forward operating base or an airfield at the wrong hour. We do not publish spares scaling or turnaround times on the site, so pin those to your fleet mix and dispersal in a briefing.

See: In-region sustainment, Request a capability brief

How does defence power sit within a wider critical-infrastructure resilience programme?

Generating sets are the layer that keeps radar, launchers, command posts and naval and airfield installations on the net when the grid or the environment fails, which is exactly the ground a resilience programme has to hold. The band runs from 2 kW to 800 kW across portable to ISO-containerised builds, so the same supplier can cover a forward base and a fixed installation. We do not claim a pre-integrated bundle with other products, but the common thread is independent origin, one accountable team and in-region sustainment. A briefing maps where these sets carry the resilience load.

See: Critical infrastructure resilience, Defence-qualified generating sets

Are these generating sets actually in operational service or only trialled?

They are in operational service. The sets are proven in national tri-service use, with a national army, navy and air force, and the 400 kW and 500 kW dual-frequency naval sets have been field-tested with a national navy on a programme where we are the sole technically and commercially qualified vendor. That is the test to put to any supplier: not what the datasheet promises but where the sets are running today, in what role, and who answers when one drops off the net. We will answer that against your operating picture in a briefing.

What are Military diesel generator sets?

Military diesel generator sets are Unstrat's Land (Land Domain) capability: A generating set on a defence platform is not a utility. It is the single point on which a radar sweeps, a launcher cycles and a command post stays on the net. These diesel generating sets cover 2 kW to 800 kW, from two-man-portable tactical units to ISO-containerised dual-frequency naval sets, each qualified against JSS 55555, MIL-STD-461 EMI control and MIL-STD-705 power quality. Proven in service with a national army, navy and air force, and available for export.

How do Military diesel generator sets work?

Military diesel generator sets deliver their effect through full band from 2 kW man-portable tactical sets to 800 kW installations, portable, skid, trolley, trailer and ISO-containerised builds, Qualified against JSS 55555, JSS 6115, CQAL 640A/B, MIL-STD-461 EMI/EMC and MIL-STD-705 power quality; DEFSTAN 08-142 and EED-Q-242 on naval programmes and Environmental envelope proven by test: operation to −30 °C, storage to −40 °C, altitude to 5,000 m, rain, dust, salt-fog and cold-start qualified, capabilities matched to the requirement and confirmed under briefing rather than published.

Who makes Military diesel generator sets?

Military diesel generator sets are built by The Defence Power Group, whose focus is defence power systems & strategic cold chain. Unstrat represents The Defence Power Group to government and enterprise buyers worldwide as an independent, non-aligned prime vendor.

Why choose Military diesel generator sets over a major-power alternative?

Military diesel generator sets are sourced from an independent, non-aligned manufacturer, so they carry no major-power disclosure rules, upgrade-locks or political ramifications. Concretely: sole technically and commercially qualified vendor for a national navy's 400/500 kW dual-frequency generating set programme. The capability is accountable to you, not to a foreign vendor's government and its release schedule.

How are Military diesel generator sets procured, and where can it be exported?

Defence power specified for survivability, not uptime: generating sets qualified against military standards from 2 kW to 800 kW, proven in national tri-service use and sold without a major-power supplier's political strings. Every engagement begins with a briefing, and export eligibility is confirmed per market under briefing rather than published. Where controlled capabilities are involved, the classification and end-user-certificate chain is confirmed first. Military diesel generator sets are then sustained in-region by one accountable team from briefing through long-term operation.
