ah-1 cobra
m28 series (emerson tat-141)
the standard fixed armament ah-1g, ah-1p (formerly referred ah-1s production), ah-1q, , initial ah-1s models, turret unit similar xm64 mentioned later in section, capable of mounting 2 m134 miniguns, 2 m129 40 mm grenade launchers, or 1 of each weapon. miniguns fitted capable of pre-set firing rates of either 2,000 or 4,000 rpm, while turret has 114 degrees of motion left or right, 17.5 degrees of elevation , 50 degrees of depression (alternate sources describe 110 degrees in azimuth, 20 degrees of elevation , 50 degrees of depression m28e1 model specifically). each minigun linked 4,000 rounds of ammunition while each grenade launcher fed 300-round magazine.
the system known have 4 standard variants, m28/a1-a3. however, actual specifics between variants vague. available information suggests specific variants mated specific iterations of ah-1 helicopter. initial xm28/m28 fitted ah-1g, m28e1/m28a1. m28a1e1/m28a2 fitted ah-1q, while m28a3 (no developmental variation known) fitted ah-1p/s helicopter. there possibility m28a2 have been first unit designed work xm128/m128 helmet sight system (hss) developed use tow armed ah-1s.
xm35/m35
an armament subsystem providing single m195 20 mm cannon on port inboard pylon of ah-1g. 950 rounds of ammunition stored in boxes faired side of aircraft. system pilot controlled, featured dual controls either pilot or gunner controlled. purpose pilot provided m73 sight.
xm64 (emerson tat-102a)
schematic of emerson tat-102a on ah-1g helicopter
the tat-102a (tactical armament turret-102a) initial main armament ah-1g helicopter, though designed interim measure. related tat-101 mentioned in uh-1 entry. turret mounts single m134 minigun 25 degrees of elevation, 90 degrees of depression, , 180 degrees of motion in azimuth, slew rate of 80 degrees per second. tat-102a designated xm64 army.
xm65/m65
the cobra missile system functional development of xm26 , tow missile system developed failed ah-56 helicopter. designed ah-1q , ah-1s cobras, ah-1f modernized cobra rebuilt use system. original iteration of system comprises launchers allowing 4 bgm-71 tow missiles per aircraft pylon carried, , tsu or telescopic sight unit, allow targeting , guidance of missile. tsu has been upgraded laat (laser-augmented airborne tow), day/night range finder, , c-nite (cobra-night imaging thermal equipment), thermal imagine/flir system ah-1s , ah-1f cobra helicopters.
m97 series , a/a49e-7 (ge universal turret)
the standard fixed armament system army s ah-1s upgunned cobra (eventually redesignated ah-1e enhanced cobra armament system or ecas) , ah-1s modernized cobra (eventually redesignated ah-1f), as, marine corps ah-1j, ah-1t, ah-1w, , ah-1z helicopters. system designed fit either m197 20 mm 3 barreled cannon or xm188 30 mm 3 barreled cannon. in practice m197 standard fit , xm188 not adopted service. turret has 110 degrees of motion in azimuth, 21 degrees of elevation, , 50 degrees of depression, slew rate in azimuth of 80 degrees per second , in elevation , depression of 60 degrees per second.
as m28 series, specifics between variants of m97 vague. 5 standard models known exist, m97/a1-a4. sources suggest individual variants of turret specific variants of ah-1 m28 series. m97a1 (and possibly m97) fitted ah-1s upgunned cobra, m97a2/a3 ah-1s modernized cobra (ah-1f), , m97a4 production ah-1fs. other sources m97a3 refitted ah-1e ecas , m97a2 initial armament ah-1s modernized cobra, agreeing m97a1 original fit ah-1s upgunned cobra. there possibility differences have associated equipment m197 cannon, including use of m89 or m89e1 delinking feeder.
the m97 fitted ah-1j, unclear if ah-1t, ah-1w, , ah-1z used variants of m97 series. subsystem used on ah-1t , ah-1w has designation in usaf s aeronautical , support equipment type designation system (asetds), a/a49e-7. turret in system designated under asetds system, gtu-1/a. how system differs army counterparts unknown. amendment official military specification, mil-f-85668(as), put out united states naval air systems command on 15 november 1995, listed a/a49e-7(v4) inactive pending new design, , listed system relevant ah-1t (tow).
xm120 (emerson tat-140)
a competing universal turret design m97 put forward emerson electric, xm120 fitted number of weapons including m60c 7.62×51mm machine gun, m134 minigun, m197 20 mm 3 barreled cannon, xm188 30 mm 3 barreled cannon, , in fact tested xm140 30 mm cannon.
ah-56 cheyenne
xm52 armament subsystem on ah-56a helicopter
xm53 armament subsystem on ah-56a helicopter
the lockheed ah-56 cheyenne got no further operational testing of ten prototypes before program cancelled.
xm51
a nose turret 1 m129 40 mm grenade launcher 300 rounds. in light of cancellation of ah-56 proposed replacement m5 system on uh-1 helicopter. designed interchangeable xm53.
xm52
belly turret single xm140 30 mm cannon. use on other helicopters debated.
xm53
a nose turret 1 7.62×51mm xm196 machine gun. said suitable uh-1 series of helicopters. designed interchangeable xm51.
ah-64 apache
m139 , area weapon subsystem
the type classified subsystem ah-64 series, m139 composed of aerial rocket control system (giving aircraft ability fire members of hydra 70/mk 66 2.75 in/70 mm rocket family), dispenser interface (controlling m130 chaff/flare dispenser, used on ah-1 helicopter), , area weapon subsystem.
the area weapon subsystem made of single m230 30 mm cannon, turret , assembly, ammunition feed, , other electronic components functioning of system. unit capable of 100 degrees of motion in azimuth left or right, 11 degrees of elevation , 60 degrees of depression, , feeds ammunition magazine 1,200 rounds.
rah-66 comanche
turreted gun system (tgs)
the rah-66 comanche intended have gun system designed jointly boeing , sikorsky. system use xm301 lightweight gun, , fed linked ammunition 500-round storage drum. turret had 120 degrees of movement in azimuth, 15 degrees of elevation , 45 degrees of depression. tgs supposed ready deployment comanche helicopter during fy04 period, cancellation of comanche ended further development of system.
