SRD-728 The AOPS shall have a primary gun weapons system
that:
a. has a calibre of between 20mm and 40mm,
b. is stabilized,
c. provides clear firing arcs over an arc of not less than
45 degrees abaft the beam on one side, through the
bow, to an arc of not less than 45 degrees abaft the
beam on the other side,
d. has elevation limits not less than 10 degrees below
the horizontal and 80 degrees above the horizontal,
e. has dual ammunition feed system that allows the
operator to select either of two types of ammunition
instantly,
f. has selectable rates of fire,
g. has the ability to display firing arcs and gun vector
line,
h. is integrated with a laser range-finding system,
i. is integrated with a single on-mount or off-mount all-
weather, day and night, electro-
optical fire control system for weapon target designation
in manual and automatic modes,
j. requires no more than a single operator,
k. receives surface target designation from the
navigation radar,
l. supports automatic collection of video and other data,
and
The gun weapons system will be selected
or detailed requirements will be developed
by PMO AOPS during definition.
The electro-optical system could include
television, IR and thermal imaging
elements and should be capable of electro-
optic surveillance independant of the gun
system.
The location of the weapon system shall
take into account maintenance
requirements, weather effects on the
system and facilitate the load/un-load and
operational use.
A gun calibre of between 20mm and 40
mm is likely appropriate.
