Cadillac Gage Turrets Descriptions

90 mm Turret

     It is a two-man turret fitted with a 90 mm Cockerill Mk III
gun or MECAR 90 mm gun, a coaxial 7.62 mm machine gun and a
commander's ring mount with a pintle-mounted 7.62 mm machine gun.
     The turret can be rotated 360 degrees under power at speeds
of up to 30 degrees per second and the 90 mm gun can be elevated
from -8 to +28 degrees at up to 30 degrees per second.  Dual
controls allow either the gunner or the commander/loader to
operate the turret and fire the main armament.  Emergency
mechanical hand-operated controls which can be used if the
electro-hydraulic controls are disabled.  The turret is fitted
with interior lighting and an extractor fan.
     The turret has external vision by means of three direct view
blocks, a commander's periscope mounted in the machine gun ring
mount that provides 360 degree rotation and a gunner's periscope
with a x8 monocular and a x1 periscope with a projectile
graticule.  For night surveillance a 200 mm, 500 000 candlepower
white light spotlight is mounted coaxially with the 90 mm gun. 
The turret armour will defeat 7.62 mm AP projectiles at zero
degrees obliquity and point-blank range.  Front turret armour is
capable of defeating 14.5 mm projectiles fired from a range of
500 meters.  The turret is provided with a stowage basket at the
rear and smoke/ fragmentation dischargers can be fitted if
required.

graticule.  For night surveillance a 200 mm, 500 000 candlepower
white light spotlight is mounted coaxially with the 90 mm gun. 
The turret armour will defeat 7.62 mm AP projectiles at zero
degrees obliquity and point-blank range.  Front turret armour is
capable of defeating 14.5 mm projectiles fired from a range of
500 meters.  The turret is provided with a stowage basket at the
rear and smoke/ fragmentation dischargers can be fitted if
required.

25 mm Turret

     The turret is of all-welded steel construction providing the
crew with complete protection from small arms fire and shell
splinters.  The commander sits on the left from the gunner on the
right, both with a single-piece hatch cover opening to the rear.
     Main armament consists of a McDonnell Douglas Helicopters 25
mm M242 Chain Gun with a 7.62 mm M240 machine gun mounted
coaxially with the main armament and a similar weapon mounted on
the turret roof for anti-aircraft defense.
     Turret traverse and weapon elevation are electro-hydraulic
with manual controls for emergency use.  An automatic deck
clearance system is provided with power override facilities.  The
weapons are fired electrically but can be fired manual in an
emergency.  As an option, full gun/ turret stabilization is
available.
     The gunner has an M36E1 day/ night sight and the commander
has eight periscopes for all-round observation.  As an option,
the commander could have six periscopes and an M36E1 day/ night
sight.
     Standard equipment includes a turret ventilation blower and
a 500 000 candlepower spotlight.

20 mm Turret

     It is a two-man armoured turret armed with a Rh 202 20 mm
automatic cannon, a coaxial 7.62 mm machine gun and a commander's
ring mount with pintle mounted 7.62 mm machine gun.
     The turret can be rotated 360 degrees under power at speeds
of up to 60 degrees per second and a minimum smooth tracking rate
of 1 mil per second.  The 20 mm gun can be elevated from -8 to
+60 degrees at up to 40 degrees per second.  Dual controls allow
either the gunner or the commander to operate the turret and fire
the main armament.  Emergency mechanical hand-operated controls
which can be used if the electro-hydraulic controls are disabled. 
The turret is also equipped with a turret ventilating blower, an
emergency firing trigger for the cannon and a rate controller
which allows firing of one, two or four rounds per second or full
automatic mode.  For night surveillance 200 mm 500 000
candlepower spotlight is mounted coaxially with the 20 mm cannon.
     The turret armour will defeat 7.62 mm AP ammunition at zero
degrees obliquity and point-blank range.

20 mm 1 Meter Turret (Mounted on Commando Scout)

     It is a one-man armoured turret armed with a Rh 202 20 mm
automatic cannon and a coaxial 7.62 mm machine gun.
     The turret can be rotated 360 degrees under power at speeds
of up to 60 degrees per second and a minimum smooth tracking rate
of 1 mil per second.  The 20 mm gun can be elevated from -8 to
+55 degrees at up to 40 degrees per second.  Emergency mechanical
hand-operated controls which can be used if the electro-hydraulic
controls are disabled.  The turret is also equipped with a turret
ventilating blower, an emergency firing trigger for the cannon
and a rate controller which allows firing of one, two or four
rounds per second or full automatic mode.  For night surveillance
200 mm 500 000 candlepower spotlight is mounted coaxially with
the 20 mm cannon.
     The turret provides all-round vision for the gunner by means
of eight direct-view vision blocks, which allow for instantaneous
360 degree vision.  The gunner's periscope is a x8 monocular
sight and unity periscope with a projectile graticule.  In
addition to the main sight the turret is equipped with an
external anti-aircraft sight.  The frontal armour of the turret
will defeat 12.7 mm AP projectiles at 425 meters the remainder
7.62 mm Ap at point-blank range and zero degrees obliquity.
 
Twin/ Combination Machine Gun (1 Meter) Turret

     It is a one-man turret capable of mounting different
configurations of weapons including twin 7.62 mm or twin 0.50
calibre machine guns and may also be equipped with a combination
of 7.62 mm/ 0.50 calibre machine guns.
     The turret is manually rotated with power option available
and can be traversed 360 degrees.  The traverse mechanism
incorporates a manual friction brake which is foot operated and a
friction drag mechanism allows it to be rotated with a fixed
position and the drag mechanism allows it to be rotated with a
fixed resistance, enabling the gunner to lay on the target more
accurately.  The weapons can be elevated from -10 to + 55 degrees
through a manual jack screw mechanism.  Ammunition is fed to the
weapons from standard ammunition boxes, eliminating the need for
feed chutes and allowing for rapid reload.  Additional ready
ammunition may be made available if the turret is not equipped
with radio sets in the turret bustle.  Weapons are fired
electrically, singly or in unison.  In the event of an electrical
failure they may be manually operated.
     The turret has a monocular M28C sight with a magnification
of x1.5 which is driven by the movement of the turret cradle,
ensuring correct sighting at all times.  All-round observation
for the gunner is by eight direct vision blocks mounted in the
upper part of the turret.  The gunner has an adjustable seat and
the turret is provided with a single-piece hatch cover that opens
to the rear and an extractor fan.  A 500 000 candlepower
searchlight is mounted coaxially with the right machine gun.
     
40 mm/ 12.7 mm Turret

     This one-man turret, a further development of the Cadillac
Gage twin/ combination machine gun (1 meter) turret, is armed
with a 40 mm Mk 19 Mod 3 grenade launcher on the left and a 12.7
mm (0.50) M2 HB machine gun on the right.
     The turret is of Cadloy ballistic steel armour, the gunner
having an M27 periscope sight with magnification of x1 and x8,
external anti-aircraft sight, eight vision blocks and a single-
piece hatch cover opening to the rear.
     A 500 000 candlepower spotlight is mounted above the 12.7 mm
M2 HMG and moves in elevation with the weapons.  A bank of 4 66 mm
electrically-operated smoke dischargers is mounted either side
of the turret rear.
