| Source measurement | — | The Ka-27PS search and rescue helicopter can carry 12 folding seats or four stretchers in its cabin, and is equipped with a 300 kg (660 lb) winch. Its fuel capacity of 3,450 litres (910 US gal; 760 imp gal) is greater than the 2,940-litre (780 US gal; 650 imp gal) capacity of the Ka-27PL.[source]Kamov Ka-27 · Design and development; only the objects and conditions stated in this passage Ka-32 variants, e.g. the Klimov-powered Ka-32A11BC, have been certified for commercial operations throughout the world, notably in Canada and Europe. The Ka-32 has been certified for the newer Klimov VK-2500 PS-02 engine.[source]Kamov Ka-27 · Design and development; only the objects and conditions stated in this passage The Ka-32A11BC features a high power-to-weight ratio and ease of handling, owing to its coaxial rotor design. The rotors' diameters are not restricted by the presence of a tail rotor and associated tail boom; this facilitates maneuvering near obstacles and helps assure exceptional accuracy when hovering in heavy smoke and dust conditions. The Ka-32A11BC may be equipped with the Bambi Bucket suspended fire-fighting system of up to five tons capacity. The service life has been extended to up to 32,000 flight hours.[source]Kamov Ka-27 · Operational history; only the objects and conditions stated in this passage In 2013, Russia tested the new Kamov Ka-27M with an active electronically scanned array radar. The basis of the modernization of the Ka-27M is installed on the helicopter airborne radar with an active phased array antenna FH-A. This radar is part of the command and tactical radar system that combines several other systems: acoustic, magnetometric, signals intelligence and radar. All the information on them is displayed on the display instrumentation.[source]Kamov Ka-27 · Operational history; only the objects and conditions stated in this passage Ka-27PS[source]Kamov Ka-27 · Variants / Military; only the objects and conditions stated in this passage (Helix-D) Search and rescue helicopter, ASW equipment removed and winch fitted.

The radar is mounted under the fuselage and provides all-around vision in the search and detection of surface, air, and ground targets. Serial upgrading of Ka-27Ms to the level of combatant helicopters was planned to begin in 2014. By the end of 2016, 46 Ka-27PLs had been scheduled for modernization, commissioned by the Russian Navy. The first eight serial Ka-27M were transferred in December 2016. Mass production approved in June 2017 and started in early 2018. A new delivery of 5 helicopters arrived in October 2018. Half of the fleet is modernized as of December 2018.
