Mk258 Mod 1
Weighing 230g, with
a muzzle velocity of
1,430m/s and maximum
dispersion of <0.4mils at
1,000m, the novel design
of the Mk258 Mod 1
enables precision shooting in
air and in water, expanding the
lethality of ship-based cannons
such as the Mk44.
“We had an idea to modify the
front section of the penetrator
to make it supercavitating –
essentially it will fly in a pocket in
the water,” said Jan Hasslid, director
of global sales and marketing for
military ammunition and shoulder-
fired systems at Nammo.
