Raws li tau hais hauv ntu dhau los ntawm kev ncig ncig ncig virtual ntawm Tsov Rog Tsov Rog ntawm Suav Kev Hloov Pauv, xyoo 1930, muaj kev ua tub rog-kev koom tes zoo ntawm lub tebchaws Yelemes thiab Tuam Tshoj. Thaum pib ntawm Sino-Japanese War xyoo 1937, Tuam Tshoj muaj tus lej German 37-mm phom tiv thaiv lub tank 3, 7 cm Pak 29. Cov phom no tau tsim los ntawm Rheinmetall AG txij xyoo 1929 thiab muaj cov log ntoo uas tsis muaj kev ncua. Tom qab ntawd, rab phom tau hloov kho tshiab thiab muab tso rau hauv kev pabcuam raws li lub npe 3, 7 cm Pak. 35/36 ib. Cannons 3, 7 cm Pak 29 thiab 3, 7 cm Pak 35/36 siv tib lub mos txwv thiab feem ntau sib txawv hauv kev mus log. Xyoo 1930, daim ntawv tso cai raug muag rau Tuam Tshoj los tsim cov phom 3, 7 cm Pak 29, thiab nws tau tsim tawm ntawm tsob ntoo loj hauv Changsha raws li lub npe Hom 30.
Qhov hnyav ntawm Hom Phom 30 hauv qhov chaw tua yog 450 kg. Kev sib ntaus tua hluav taws - txog 12-14 rds / min. Ib rab phom-tho qhov projectile hnyav 0, 685 g tawm ntawm lub thoob nrog qhov pib nrawm ntawm 745 m / s thiab ntawm qhov deb ntawm 500 m raws qhov ib txwm tuaj yeem nkag mus rau 35 mm cov cuab yeej tiv thaiv. Ua raws li qhov tseeb tias cov tub rog Nyij Pooj, sib ntaus hauv Suav teb, tsis muaj cov tso tsheb hlau luam nrog cov cuab yeej tiv thaiv phom loj, rab phom 37-mm ntawm tus qauv German yog txoj hauv kev zoo rau kev tiv thaiv tiv thaiv lub tank.
Hauv thawj lub sijhawm ua tsov rog hauv Suav Teb, Imperial Japanese Army siv Hom 89 tso tsheb hlau luam nruab nrab (qhov siab tshaj plaws tiv thaiv txheej tuab 17 hli), Hom 92 lub teeb tso tsheb hlau luam (qhov siab tshaj plaws tiv thaiv tuab 6 hli), Hom 95 lub teeb tso tsheb hlau luam (siab tshaj plaws tiv thaiv tuab 12 hli) thiab Hom 94 tankettes (qhov siab tshaj plaws ntawm cov cuab yeej tuab 12 hli). Cov cuab yeej tiv thaiv ntawm txhua lub tsheb ntawm qhov chaw tua hluav taws tuaj yeem nkag mus tau yooj yim los ntawm 37-mm projectile. Txawm li cas los xij, vim tias muaj pes tsawg tus neeg, koom haum tsis zoo thiab npaj tsis zoo ntawm Suav pab tub rog, Hom 30 rab phom tiv thaiv lub tank tsis muaj txiaj ntsig ntau rau kev ua phem.
Lwm qhov phom tiv thaiv lub tank ntawm German keeb kwm hauv kev sau los ntawm Tsev khaws puav pheej Tub Rog ntawm Suav Kev Tawm Tsam yog 50-hli phom tiv thaiv lub tank 5 cm Pak. 38.
Hmoov tsis zoo, cov ntaub ntawv xov xwm tsis cuam tshuam txog keeb kwm ntawm kev pom cov riam phom no hauv Suav teb. Nws yog qhov ua tau tias 5 cm Pak. 38 tau xa mus rau PRC thaum ntxov xyoo 1950 rau siv los ntawm Suav pab dawb hauv Kauslim Teb. Nws tau paub tias Suav thiab North Kauslim pawg uas tawm tsam UN cov tub rog nquag siv ntes German caj npab me me thiab rab phom loj uas xa los ntawm Soviet Union. Txawm hais tias suav nrog kev siv cov phom loj tiv thaiv phom loj ntawm Kaus Lim Kauslim, 5 cm Pak. 38 sawv cev rau qee qhov nqi sib ntaus.
Ntawm qhov deb ntawm 500 m, 50-mm cov cuab yeej tiv thaiv qhov projection hnyav 2 kg, nrog qhov pib nrawm ntawm 835 m / s, ib txwm tuaj yeem nkag mus rau 78 hli tuab cov cuab yeej ua rog. Yog li, 5 cm Pak. 38 muaj lub sijhawm tseeb los tsoo American M4 Sherman lub tank. Cov neeg ua haujlwm tau kawm paub zoo tuaj yeem muab tus nqi sib ntaus ntawm cov hluav taws mus txog 15 rds / min. Qhov tsis zoo ntawm qhov riam phom no nrog lub zog me me yog nws qhov hnyav, uas mus txog 840 kg hauv qhov chaw sib ntaus. Qhov ntawd ua rau nws nyuaj rau yob hla qhov av ntxhib los ntawm cov zog ntawm kev suav.
Ntxiv rau cov neeg German, lub tsev khaws khoom khaws cia muaj cov phom Japanese tiv thaiv lub tank ntawm 37-47 mm. Xyoo 1936, Nyij Pooj tau pib tsim ntau ntawm 37-mm Hom 94 phom tiv thaiv lub tank. Ib rab phom loj 37-hli rab phom hnyav 645 g nrog qhov pib ceev ntawm 700 m / s, ntawm qhov deb ntawm 450 m raws qhov ib txwm tuaj yeem nkag tau 30 hli ntawm cov cuab yeej tiv thaiv. Qhov hnyav ntawm rab phom hauv txoj haujlwm sib ntaus yog 324 kg, hauv txoj haujlwm thauj - 340 kg. Tus nqi hluav taws kub txog 20 rds / min. Muaj cov ntaub ntawv foob pob zoo thiab tus nqi hluav taws rau nws lub sijhawm, rab phom 37 hli Hom 94 muaj tus qauv tsim qub hauv ntau txoj hauv kev. Kev mus los uas tsis tau tawg thiab ntoo, cov log hlau tsis tau tso cai rau nws rub los ntawm kev kub ceev. Txog rau thaum ib nrab ntawm xyoo 1943, tau tsim ntau tshaj 3400 rab phom.
Xyoo 1941, tau hloov kho tshiab ntawm rab phom tiv thaiv lub tank, hu ua Hom 1, tau siv. / s.
Txawm hais tias cov cuab yeej nkag mus rau ntawm 37-mm Hom 1 rab phom twb tsis txaus nyob rau thaum xyoo 1940s, 2,300 daim ntawv tau tsim los ntawm lub Plaub Hlis 1945.
Ib tus neeg 37-hli phom tiv thaiv lub tank tau qee zaum raug ntes los ntawm Kuomintang thiab cov tub rog sib tua thaum Tsov Rog Sino-Japanese. Ntau tshaj ob puas lub phom loj 37-mm tau muab pov tseg ntawm PLA tom qab kev kov yeej Kuomintang. Txawm li cas los xij, thaum pib xyoo 1950, cov riam phom no tsis muaj kev cia siab thiab siv feem ntau yog rau kev qhia paub.
Xyoo 1939, rab phom tiv thaiv 47-mm Hom 1 tau siv nyob hauv Nyij Pooj. Qhov no ua rau nws muaj peev xwm muab kev rub nrog cov neeg kho tshuab traction. Qhov hnyav ntawm rab phom 47-mm hauv qhov chaw tua yog 754 kg. Thawj qhov ceev ntawm 1.53 kg ntawm cov cuab yeej tiv thaiv cov cuab yeej cuab tam yog 823 m / s. Ntawm qhov deb ntawm 500 m, qhov projectile, thaum tsoo ntawm lub kaum sab xis, tuaj yeem nkag mus rau 60 mm ntawm cov cuab yeej ua rog.
Txog rau xyoo 1930 lig, Hom Phom 1 tau ua raws li qhov yuav tsum tau ua. Txawm li cas los xij, kev sib ntaus sib tua tau pom tias cov cuab yeej tiv thaiv pem hauv ntej ntawm Asmeskas lub tank nruab nrab tuaj yeem nkag mus tas li ntawm qhov deb tsis tshaj 200 m. tua ntawm lub zog thiab lub zog tiv thaiv lub teeb. Ua ntej kawg Kev Tsov Rog Thoob Ntiaj Teb Zaum Ob, kev lag luam Nyij Pooj tau xa txog 2300 47-mm Hom 1 phom. Xyoo 1950.
Kev nthuav qhia ntawm Tsev khaws puav pheej Tub Rog ntawm Suav Kev Tawm Tsam nthuav tawm 40 thiab 57-hli phom tiv thaiv lub tank ntawm Askiv kev tsim khoom: QF 2 pounder thiab QF 6 pounder.
40 mm QF 2 rab phom rab phom muaj tus qauv qub heev. "Ob-pounder" hauv kev sib ntaus sib tua tau so ntawm lub hauv paus qis hauv daim ntawv ntawm lub tswb, vim tias lub kaum sab xis qhia ntawm 360 ° tau ua kom ntseeg tau, thiab lub log tau rub tawm hauv av thiab tsau rau sab. Tom qab hloov mus rau txoj haujlwm sib ntaus, rab phom tuaj yeem yooj yim tig mus rau txhua qhov chaw, tso cai rau tua ntawm kev txav cov tsheb tiv thaiv lub tsheb mus rau txhua qhov chaw. Muaj zog nplaum rau hauv av ntawm cruciform puag tau nce qhov kev ua haujlwm zoo, vim tias rab phom tsis "taug kev" tom qab txhua qhov kev tua, ua kom nws lub hom phiaj. Ob-phaus tau zoo dua 37-mm German phom tiv thaiv lub tank 3, 7 cm Pak 35/36 hauv ntau txoj hauv kev. Tib lub sijhawm, hauv kev sib piv nrog ntau rab phom ntawm lub sijhawm ntawd, kev tsim qauv ntawm Askiv 40-mm rab phom yog qhov nyuaj heev, ntxiv rau, nws hnyav dua li lwm yam phom tiv thaiv lub tank. Qhov hnyav ntawm rab phom hauv qhov chaw sib ntaus yog 814 kg. Ib rab phom-tho 1, 08-kg projectile uas tawm ntawm rab phom phom ntawm qhov ceev ntawm 850 m / s, ntawm qhov deb ntawm 457 m, nkag mus rau 50-mm homogeneous armor. Tus nqi hluav taws kub yog 20 txhaj tshuaj / min.
Yuav ua li cas British-ua 40-mm rab phom tau xaus rau hauv Suav Tsev khaws puav pheej tsis meej. Tej zaum rab phom tau raug ntes los ntawm pab tub rog Nyij Pooj nyob hauv ib ntawm cov tebchaws Askiv nyob rau sab Hnub Tuaj Sab Hnub Poob, thiab tom qab ntawd, tom qab Nyij Pooj tau swb, nws tau muab pov tseg los ntawm Suav.
Keeb kwm ntawm 57 mm QF 6 phom phom loj yog pob tshab dua. Six-Pounder tau raug ntes los ntawm Suav pab dawb thaum sib ntaus sib tua ntawm Kaus Lim Kauslim. Lub tsev khaws khoom nthuav tawm nthuav qhia kev hloov kho ntawm QF 6 lub tshuab nqus tsev Mk IV nrog lub tog raj ntev nrog nruab nrog lub qhov ncauj nres.
Thawj tus tiv thaiv lub tank "rau-pounders" nkag mus rau cov tub rog thaum lub Tsib Hlis 1942. Lub sijhawm ntawd, "rau-phaus" yooj yim daws nrog txhua lub tank yeeb ncuab. Ib rab phom-tho 57-mm projectile uas hnyav 2, 85 kg ntawm 500 m, thaum tsoo ntawm lub kaum sab xis 60 °, tso siab rau khov 76 mm cov cuab yeej. Xyoo 1944, APCR lub plhaub nrog 120-140 mm ib txwm nkag los ntawm qhov deb ntawm 900 m tau tshwm sim. Tsim ntawm rab phom 6-pounder tau yooj yim dua li ntawm 2-pounder. Lub txaj bifurcated muab lub kaum sab xis qhia ntawm 90 °. Qhov hnyav ntawm rab phom hauv qhov chaw tua yog 1215 kg. Tus nqi hluav taws - 15 rds / min. Los ntawm 1942 txog 1945, ntau dua 15,000 rau-pounders tau tsim. QF 6 phom phom tau ua haujlwm nrog pab tub rog Askiv txog rau thaum xyoo 1950 thiab tau siv rau lub sijhawm Tsov Rog Kauslim.
Qhov kawg ntawm 1941, thawj 37-mm M3A1 phom tiv thaiv lub tank tau tshwm sim hauv Suav teb. Hauv nws chav kawm, nws yog rab phom zoo heev, tsis zoo li German 3, 7 cm Pak. 35/36 ib. Txawm li cas los xij, Asmeskas 37-mm rab phom los ntawm xyoo 1940s tawm tsam keeb kwm yav dhau los ntawm Nyij Pooj 47-mm Hom 1 thiab German 50-mm 5 cm Pak. 38 saib daj ntseg. Txawm li cas los xij, kev tsim cov phom 37 hli txuas ntxiv mus txog rau thaum xyoo 1943. Los ntawm 1940 txog 1943, ntau dua 18,000 37 mm phom tiv thaiv lub tank tau raug rho tawm hauv Tebchaws Meskas.
Txawm hais tias nyob hauv North Africa thiab Ltalis, rab phom 37-mm tau ua haujlwm nruab nrab, lawv ua tiav tawm tsam tiv thaiv cov tub rog Nyij Pooj uas tsis muaj zog nyob hauv Asia thiab tau siv kom txog rau thaum muaj kev tawm tsam. Lub zog ntawm 37-mm lub plhaub yog txaus txaus los kov yeej cov cuab yeej nyias ntawm Japanese tso tsheb hlau luam. Nyob rau tib lub sijhawm, M3A1 rab phom raug nqi tsawg dua 57- thiab 76-hli phom tiv thaiv lub tank, kev ua kom zoo dua qub, kev cog lus thiab muaj peev xwm rub los ntawm Willys MB jeep kuj yog qhov tseem ceeb. Nrog qhov hnyav txog 400 kg, rab phom 37-mm tuaj yeem txav thiab npog los ntawm cov neeg coob, uas yog qhov tshwj xeeb tshaj yog nyob rau sab nraud ntawm txoj kev ntawm hav zoov-cov ntoo loj. Ntxiv nrog rau kev sib ntaus sib tua tsheb tiv thaiv, 37-mm M3A1 rab phom tau siv los ua riam phom pab tub rog ncaj qha. Hauv qhov xwm txheej tom kawg, lub zog qis ntawm qhov tawg ntawm qhov hnyav 0.86 kg, muaj 36 g ntawm TNT, txwv tsis pub nws ua tau zoo, tab sis tiv thaiv kev tawm tsam loj heev ntawm cov tub rog Nyij Pooj, cov txiv hmab txiv ntoo tua nrog 120 lub mos txwv hlau tau ua pov thawj nws tus kheej zoo.
Txog rau Asmeskas 37-hli phom tiv thaiv lub tank, ob hom riam phom-tho qhov zoo li tau tsim. Thaum pib, cov mos txwv thauj khoom suav nrog kev txhaj tshuaj nrog qhov hnyav ntawm 0.87 kg, uas muaj qhov pib nrawm ntawm 870 m / s. Ntawm qhov deb ntawm 450 m raws qhov ib txwm muaj, nws tau hlais 40 hli cov cuab yeej ua rog. Tom qab ntawd, lub projectile tau saws nrog qhov nce muzzle nrawm thiab nruab nrog lub taub hau ntsaws. Kev nkag mus ntawm qhov projectile no tau nce mus rau 53 mm.
Txog thaum xyoo 1947, cov neeg Asmeskas tau muab Kuomintang nrog txog 300 37-mm phom tiv thaiv lub tank. Feem ntau ntawm lawv tau raug ntes los ntawm cov neeg Suav liab. Cov phom no tau siv nyob rau thawj lub sijhawm muaj kev tawm tsam hauv Kaus Lim Qab Teb, thiab raws li kev qhia phom tau ua haujlwm nrog PLA txog thaum ib nrab xyoo 1960.
Kev sib ntaus sib tua nyob rau lub caij ntuj sov xyoo 1943 hauv Sicily thiab sab qab teb Ltalis tau qhia txog kev ua tsis tau zoo ntawm Asmeskas 37-mm rab phom tiv thaiv cov tub rog German nruab nrab. Hauv nruab nrab xyoo 1943, cov neeg Asmeskas tau txiav txim siab tsim cov M3A1, hloov nws ntawm kab sib dhos nrog rab phom 57-mm M1, uas yog hloov kho me ntsis ntawm Askiv rau-phaus. Tom qab ntawd, kev hloov kho ntawm M1A1 thiab M1A2 tau tshwm sim, suav nrog kev txhim kho txheej txheem kev taw qhia kab rov tav. Txog thaum kawg Tsov Rog Ntiaj Teb Zaum Ob, ntau dua 15,000 rab phom tau tsim los ntawm Asmeskas kev lag luam. Hais txog nws cov yam ntxwv tseem ceeb, Asmeskas 57-mm rab phom tiv thaiv lub tank tau ua tiav raws li cov lus Askiv qub.
Ua raws li qhov tseeb tias lub mos txwv thauj khoom suav nrog qhov tawg ntawm qhov hnyav 2.97 kg, muaj txog 200 g ntawm cov khoom tawg, 57-mm phom tiv thaiv lub tank tuaj yeem siv tau tiv thaiv tib neeg lub zog. Nws yog lub luag haujlwm no uas tau siv phom rau cov tub rog ntawm Generalissimo Chiang Kai-shek. M1A2 rab phom kuj tseem muaj nyob hauv UN cov tub rog ua haujlwm ntawm Kaus Lim Kauslim. Ob peb Asmeskas-ua 57mm rab phom tau raug ntes los ntawm PLA.
Lub tsev khaws khoom pov thawj tseem muaj cov phom ua rog tiv thaiv lub tebchaws Soviet thiab lawv cov neeg Suav. Txij xyoo 1937 txog 1941, Tuam Tshoj tau txais ntau pua lub Soviet 45-mm phom tiv thaiv lub tank 1934 thiab Qauv 1934. 1937 45-mm phom tiv thaiv lub tank tau tsim los ntawm 37-mm rab phom ntawm 1930 tus qauv (1-K), uas, nyeg, tau tsim los ntawm lub tuam txhab German Rheinmetall-Borsig AG thiab muaj ntau yam nrog phom tiv thaiv lub tank 3, 7 cm Pak 35/36.
Xyoo 1930s lig, rab phom 45-mm yog rab phom tiv thaiv lub tank niaj hnub no, nrog cov cuab yeej zoo nkag mus thiab siv tau qhov hnyav thiab tus yam ntxwv zoo. Nrog rau qhov hnyav hauv txoj haujlwm sib ntaus ntawm 560 kg, kev suav ntawm tsib tus neeg tuaj yeem yob nws hla qhov luv kom hloov txoj haujlwm. Cov yam ntxwv ntawm rab phom ua rau nws muaj peev xwm ua tiav kev sib ntaus ntawm txhua qhov kev npaj rau tua hluav taws nrog cov tsheb tiv thaiv tiv thaiv los ntawm cov cuab yeej tiv thaiv mos txwv. Ntawm qhov deb ntawm 500 m, lub foob pob ua ntxaij foob pob hluav taws tau hla 43-mm cov cuab yeej thaum lub sijhawm ntsuas ib txwm muaj. Thawj qhov nrawm ntawm rab phom-tho qhov projectile hnyav 1, 43 kg yog 760 m / s. Cov mos txwv thauj khoom kuj suav nrog kev tawg thiab cov txiv hmab txiv ntoo txhaj tshuaj. Lub foob pob tawg tawg hnyav 2, 14 kg muaj 118 g ntawm TNT thiab muaj thaj tsam puas ntsoog nrog txoj kab uas hla ntawm 3-4 m. Tus nqi hluav taws ntawm rab phom 45-mm yog 15-20 rds / min.
Xyoo 1942, rab phom tiv thaiv 45-mm M-42 tau txais los ntawm Red Army. Piv rau cov piv txwv ua ntej ntawm tib lub peev xwm, nws tau nce kev nkag mus rau tej cuab yeej. Qhov no tau ua tiav los ntawm kev ua kom ntev lub thoob thiab los ntawm kev siv cov mos txwv muaj zog dua, uas ua rau nws muaj peev xwm nce qhov muzzle nrawm ntawm rab phom-tho qhov projectile mus rau 870 m / s. Ntawm qhov deb li ntawm 500 m, cov cuab yeej tiv thaiv phom sij feem ntau nkag mus rau 61 mm ntawm cov cuab yeej ua rog. Nrog rau kev ncua deb ntawm 350 m, lub foob pob hluav taws me me tuaj yeem nkag mus rau 82 mm tuab cov cuab yeej tiv thaiv. Los ntawm nruab nrab xyoo 1943, vim muaj kev tiv thaiv ntau ntxiv ntawm German tso tsheb hlau luam, M-42 rab phom tiv thaiv lub tank tsis tau ua tiav raws li qhov xav tau, vim tias tus nqi tsim khoom qis, kev txav mus tau zoo thiab yooj yim ntawm camouflage ntawm qhov chaw tua, nws siv txuas ntxiv mus txog thaum kawg ntawm kev ua siab phem. Los ntawm 1942 txog 1946, 11,156 M-42 phom tau tsim hauv USSR.
Tom qab Kev Tsov Rog Thoob Ntiaj Teb Zaum Ob Kawg, Soviet Union tau muab rau Suav cov neeg sib tawm tsam txog 1,000 M-42 phom tiv thaiv lub tank. Riam phom ntawm hom no tau nquag siv los ntawm PLA thaum Tsov Rog Kauslim. Qhov hnyav hauv qhov chaw tua ntawm 620 kg ua rau nws muaj peev xwm nqa phom mus rau saum toj siab yam tsis siv lub tshuab siv zog. Raws li txoj cai, 45-mm cov phom loj tau txhawb nqa cov tub rog nrog hluav taws, tab sis nyob rau qee kis lawv tau ua tiav siv tiv thaiv Asmeskas cov tsheb tiv thaiv. Txawm hais tias rab phom M-42 tsis muaj kev cia siab dhau los ntawm ib nrab xyoo 1950, lawv cov kev pabcuam hauv PLA cov chav sib ntaus txuas ntxiv mus txog rau ib nrab xyoo 1960.
Qhov phom sij ntau dua rau txhua tus, tsis suav nrog, Asmeskas thiab Askiv cov tso tsheb hlau luam uas tawm tsam Kaus Lim Kauslim, yog 57-hli cov cuab yeej phom-phom los ntawm ZiS-2 rab phom.
Raws li lub rooj nkag mus rau cov cuab yeej tiv thaiv, 57-mm cov cuab yeej tiv thaiv qhov projectile hnyav 3, 19 kg nrog qhov pib nrawm ntawm 990 m / s ntawm 500 m feem ntau nkag 114 mm ntawm cov cuab yeej. Subcaliber armor-piercing projectile ntawm ib txoj hlua-rau-reel zoo uas hnyav 1.79 kg nrog qhov pib nrawm ntawm 1270 m / s nyob rau tib qhov xwm txheej tuaj yeem nkag mus rau 145-mm armor. Cov mos txwv tseem muaj cov tshuaj tua nrog cov tawg tawg hnyav txog 3, 75 kg, muaj 220 g ntawm TNT. Ntawm qhov deb li ntawm 400 m, buckshot tuaj yeem siv rau tiv thaiv cov yeeb ncuab tub rog.
Tus naj npawb tseeb ntawm 57-mm ZiS-2 cov phom xa mus rau Tuam Tshoj tsis paub, tab sis xyoo 1955, PRC tau pib tsim khoom ntau ntawm Suav cov ntawv tso cai sib piv hu ua Hom 55. Tau 10 xyoo, Suav kev lag luam tsim tawm txog 1000 57-mm Hom 55 phom tiv thaiv lub tank, uas tau ua haujlwm kom txog rau thaum ntxov xyoo 1990.
Txhawm rau tua cov tso tsheb hlau luam thaum Tsov Rog Kauslim, faib 76, 2-mm ZiS-3 rab phom kuj tau siv. Cov cuab yeej tiv thaiv rab phom uas hnyav 6, 5 kg tau pib ua ntej ntawm 655 m / s, thiab ntawm qhov deb ntawm 500 m raws qhov ib txwm nws tuaj yeem nkag mus rau 68 mm ntawm cov cuab yeej ua rog. Ib rab phom me me, uas hnyav 3.02 kg, tawm hauv lub thoob ntawm qhov nrawm ntawm 950 m / s, tau hle 85 mm cov cuab yeej ua rog nyob rau tib qhov deb raws qhov ib txwm muaj. Qhov no txaus los swb M4 Sherman cov tso tsheb hlau luam nruab nrab, tab sis cov cuab yeej tiv thaiv pem hauv ntej ntawm M26 Pershing thiab M46 Patton tso tsheb hlau luam rau 76, 2 hli lub plhaub tsis tuaj yeem tiv taus.
Kev nkag mus tsis txaus ntawm cov cuab yeej-tho thiab sub-caliber zoo li tau them ib nrab los ntawm qhov muaj ib puag ncig nrog cov phom sib sau ua ke hauv cov mos txwv, uas, yog tias tsoo ntawm lub kaum sab xis, tuaj yeem nkag mus rau 90-100 mm tuab tuab. Txij li ib nrab ntawm xyoo 1952, Suav cov neeg tuaj yeem pab dawb siv 76, 2-mm ZiS-3 phom feem ntau yog tua los ntawm txoj haujlwm kaw.
Tom qab qhov kawg ntawm kev ua phem rau Kaus Lim Qab Teb Kauslim, PLA cov lus txib tau txhawj xeeb nrog kev nce kev sib ntaus ntawm cov phom loj tiv thaiv lub tank. Hauv qhov no, tsis pub dhau lub moj khaum ntawm kev koom tes ua tub rog-txuj ci nrog USSR, tau muab ntau lub kaum ob rab phom 85-mm D-44 los tiv thaiv lub tank.
Kev txhim kho ntawm D-44 phom tiv thaiv lub tank pib thaum Tsov Rog Loj Patriotic; nws muaj peev xwm saws tau riam phom tsuas yog xyoo 1946. Sab nrauv, D-44 zoo ib yam li German 75-mm anti-tank Cancer 40. Ua ntej qhov kawg ntawm kev tsim khoom xyoo 1956, ntau tshaj 10,000 units tau tsim. Qhov hnyav ntawm rab phom hauv qhov chaw sib ntaus yog 1725 kg. Kev sib ntaus tua hluav taws 15 rds / min. Ib rab phom-tho qhov projectile hnyav 9, 2 kg muaj qhov pib nrawm ntawm 800 m / s, thiab nyob deb li ntawm 1000 m raws qhov ib txwm nws tuaj yeem nkag tau rau hauv 100 cov cuab yeej. Ib rab phom me me uas hnyav 5, 35 kg tawm ntawm lub thoob nrog qhov pib nrawm ntawm 1020 m / s thiab ntawm qhov deb ntawm 500 m, thaum tsoo ntawm lub kaum sab xis, tho 140 mm ntawm cov cuab yeej ua rog. Qhov projectile sib sau ua ke, tsis hais txog qhov ib txwm muaj, nkag mus rau hauv 210-mm armor.
