capacity of not less than 40 T to enables
sustenance when the ship is employed in
shallow waters (up to 20 m depth).
18. Cold and Cool Rooms Cold and Cool rooms to carry fresh victuals for
at least 30 days and dry provision store to keep
rations for at least 45 days should be provided.

19. Weapons
(a) SSM Complex.
The ship should carry a
minimum of 08 SSMs.
(b) SAM System.
The ship should be fitted with
a SAM for providing credible near 360 degree
AMD coverage to the ship. It should be able to
engage the sea skimming missiles, flying 3-5 m
above sea level, upto max speed of 3 Mach.
@Penguin means Barak 8???
(c) MR Gun System. A gun with a stealth feature
having range not less than 15 km and capability
to carry out SU, AA and AMD engagements
should be fitted. It should have the facility to be
remotely operated using FCRs as well as EO
(Electrical-Optical) sight.
(d) CIWS. The CIWS should both radar and EO
(Electro-Optically) guided to double up as LIMO
weapons. The placement of CIWS should be
such that it provides near 360 degree AMD
protection without requirement of course
alteration.
(e) Chaff. The ship should be fitted with suitable
