The DAS-10 Cormorant helicopter series was designed by Detmerian Aerospace to replace AgustaWestland EH101 helicopters serving in the Isselmere-Nielander Army and Royal Isselmere-Nieland Navy as medium-lift and anti-submarine helicopters as well as for heliborne early warning. Anti-submarine versions of the Cormorant were to have a payload of at least 1500 kg — in order to carry at least four weapons of 350 kg on its fuselage-mounted weapon stubs — and have superior sensor systems enabling it to counter enemy submarines and other threats.

DAS-10C medium lift helicopter
The DAS-10C medium-lift helicopter (MLH) variant is commonly referred to as the base model of the design. Despite being able to transport up to a platoon (43 soldiers), both the INA and the RINM prefer it to transport half-platoon detachments as well as any other equipment operational contigencies might require.
Service designation: HC.3
Weights: empty: 7873 kg; clean: 11045 kg (4 fuel tanks full); armed (2 × 7.62mm GPMG side guns): 11105.2 kg; troop carrier: 14555 kg; maximum take-off: 14800 kg; alternative gross weight: 15800 kg
Payload: 27 troops, 3000 kg (internal), 5443 kg external (slung)
DAS-10D drone control helicopter
The DAS-10D drone control (DCH) variant was designed to support the operation of uncrewed aerial and/or ground vehicles, in particular those used by the Isselmere-Nielander Army and the Royal Isselmere-Nieland Marines.
Service designation: HQ.5
DAS-10E signals intelligence and surveillance helicopter
Service designation: HE.4
DAS-10M maritime patrol helicopter
The Royal Isselmere-Nieland Navy wanted the DAS-10M maritime patrol variant to be able to carry four air-dropped GWS.63 Barracuda torpedoes with four full fuel tanks with 4100 litres of JP-8. In practice, most RINN anti-submarine patrols operate with three tanks containing a total of 3230 litres as well as the four lightweight torpedoes, although in wartime greater endurance takes precedence over payload.
Service designation: HM.1
Sensors: 360° search radar (ARS.282 Scrimshaw), weather radar (ARN.239), forward optronic search and target turret (FOST, ASU.280; infra-red, low light-level television-charge coupled device (LLLTV-CCD), laser), towed magnetic anomaly detector (MAD, ASQ.117), sonobuoys (40), dipping medium-low frequency sonar (AQS.209)
Weights: Empty: 9208.68 kg; clean: 12510.68 kg; equipped (sonobuoys): 13218.28 kg; mission weight (4 x GWS.63A Barracuda torpedoes): 14518.28 kg; maximum take-off: 14800 kg; alternative gross weight: 15800 kg
Payload: 1300 kg of weapons on two stub wings; may be fitted with one or two door general purpose machine gun mount(s)
DAS-10W heliborne early warning
Heliborne early warning (HEW)
Service designation: HEW.2
Sensors: 360° search radar (ARS.283), weather radar (ARN.239), FOST turret (ASU.280; IR, LLTV-CCD, laser)
Weights: empty: 9367.4 kg; 12671.4 kg; maximum take-off: 14800 kg; alternative gross weight: 15800 kg
Payload: 1300 kg of weapons on two stub wings; may be fitted with one door GPMG mount
