Not the most ingenious patch. Not the worst, either.

Kamov Ka-66PL

A unit meant to turn a techno-thriller into a horror story.

NAJSA reporting name: Harpy

Locomotion: helicopter

Squad size: single craft

Special abilities:

  • Go Dark
  • Sub Search Mode - on by default; craft maintains lowered speed and low altitude, and drops sonobuoys; ability disabled once the supply of sonobuoys is drained.


The Russian Navy loves Kamov's contrarotating propeller helis. Having a lower rotor diameter and being able to hover steadily all make them prime candidates for deck-based helicopters.

Ka-66 is heavier than any other of preceding models (barring, of course, USMC's Super Stallions and the like, which are dedicated heavy transports), but that allows to overcome the misgivings of the old Ka-27, a helo so small it could carry either sonobuoys or sensors.

Transport Capability

Can be used to ferry an Admiral.


A fairly good kit of Mk 1 Eyeball and NVGs for standard operations is combined with a radome under the nose for a ground-search X-band radar, two stub wing-mounted sonobuoy containers with 60 passive and active buoys and an SPO-15 passive radar station.

  1. FLIR - Forward-Looking Infrared can spot thermal emissions from nuclear-powered subs at periscope depths.
  2. Magnetic Anomalies Detector - a characteristic boom under the tail can spot a submarine directly under the craft. Aside from that, most modern submarines are either small, or made from non-magnetic materials, or have magnetic field suppressors.
  3. ElInt Station - L-215 passive radar system with additional antennae and a database of common radar systems; ASW helicopters can provide early warning of incoming surface ships, not to mention they make use of periscope-mounted radars suicidal.
  4. Dipping Sonar - mounted in the central compartment just one bulkhead from the sonar operator, it's a combination of a winch, kevlar-reinforced cable/wire and a passive-active sonar unit. Works every time the helicopter enters hovering mode; adds special ability "Go Active (SONAR)".


Its stub wings have two weapon hardpoints. By default, they carry eight PLAB-250-120 proximity-triggered depth charges, which can cause trained sub captains to look rather stupid when they resort to counter-torpedo tactics.

  1. UMGT-2 – with “U” standing for “standardised”, I’m going to leave this 400 mm guided torpedo for Project 2038 to describe. Needless to say, you’ll be seeing it, ballute-retarded, rocket- or missile-delivered, everywhere.
  2. RBK-100/PLAB-10K – four cluster bombs with 6 shaped-charge submunitions each, “just in case.”
  3. AA Missiles – 9K38 Igla shoulder-fired missiles, twin racks over each of the two sonobuoy pods.


It doesn't happen to have ejection seats, or built-in chaff-flare launchers. Aside from that, considering the amount of firepower that gets thrown around in a naval engagement, any armour is pointless. And it’s not like the subs would shoot back… right?


The Ka-66 shares tried and tested Kamov engineering elements with Ka-65, with a pair of TVZ-117 turboshafts spinning two counterrotating propellers. This design excludes the need for a tail rotor, leaving it with two vertical stabilisers and a fuel tank.

  1. Flawless carbon composite turbines - increased thrust
  2. Supplemental fuel tank - increased range
  3. Directed exhaust - the limited thrust generated by the turbines is optimised for horizontal thrust.
