The MH-60R is employs a single operator to handle both tactical and accoustic functions in the rear of the aircraft. This "integrated sonics" approach offers some advantages including requiring one less crew member but it does not meet the criteria for dual operators for the Indian navy. The mission system operator interface and overall design (Done by Lockheed Martin) has been criticized by operators and pilots as not being very user friendly and other info indicates on going problems with the system. An upgrade is in the works including adding a track ball to enhance operator interaction with the system but in initial testing this has received only luke warm reviews by the crews.
I do not know pricing and I have already touched on some of the issues that might affect price. All those details are handled by Sikorsky and likely already provided to the Indian customer. As far as differences and commanlities:
1. S-70B has the Penguin Anti-Ship missile already integrated, the 60R does not.
2. Both have the American MK-46 & MK-54 torpedoes already integrated. The 70B also has the Eurotorp A244 mod 3 torpedo integrated.
3. The 70B AFCS is a new system that represents a significant improvement over earlier Seahawk systems.
4. The new WMS facilitates integration of indigenous systems or unique customer required stores or weapons.
5. The 70B employs a "federated systems architecture" meaning major functions are dispersed to centralized subsystems. Modification enhancement has typically proved to be easier, cheaper, and less risk for systems of this type, while the 60R employs a "centralized architecture" with a primary and backup mission computer that performs all mission related functions ( mission management, flight management, weapons management, navigation, etc.)
6. Both have integrated FLIR, ESM, counter measures, Radar, EGI (embedded GPS with inertial) navigation and attitude reference systems, and AFCS systems. I believe the 60R does not currently have a VOR/TACAN navigation capability.
The Indian navy has flown the 70B extensively during evaluations for the current MRH tender and has also flown the 60R to a lessor degree. I believe they have all the information they need to make an informed and appropriate decision.
