Cov tub rog tiv thaiv huab cua hauv tebchaws Finnish siv hauv Kev Tsov Rog Thoob Ntiaj Teb tau muaj tus lej me me, txawm hais tias feem ntau muaj cov phom tiv thaiv dav hlau me me rau lub sijhawm ntawd yog niaj hnub no. Tab sis tib lub sijhawm, tsis muaj rab phom tiv thaiv lub dav hlau tshiab ntawm nruab nrab thiab qhov loj, uas ua rau nws nyuaj rau tshem tawm cov kev tawm tsam los ntawm Soviet cov foob pob ua haujlwm ntawm nruab nrab qhov siab.
Thawj rab phom tiv thaiv dav hlau nruab nrab ntawm Finnish tiv thaiv huab cua yog 75 hli Kane rab phom thiab 76 hli phom tiv thaiv dav hlau. 1914/15 (3, Qiv phom tiv thaiv dav hlau). Thaum pib muaj kev ua phem rau xyoo 1939, me ntsis ntau dua peb caug 75 thiab 76 mm phom tau ua haujlwm. Kane's 75 hli rab phom loj tau teeb tsa feem ntau ntawm cov peev txheej ntawm cov roj teeb ntawm ntug dej hiav txwv. Cov phom 75 hli, hloov kho thiab yoog raws rau hluav taws tiv thaiv dav hlau, tseem hu ua 75 hli Zenit-Meller.
Lender cov phom tau teeb tsa ntawm cov tsheb ciav hlau. Qhov kawg ntawm 30s, cov phom loj no tsis muaj kev cia siab, qhov ntau thiab qhov siab ntawm lub hom phiaj ntaus tsis tau raws li qhov xav tau niaj hnub no, thiab tseem ceeb tshaj, tsis muaj cov cuab yeej tswj hluav taws rau phom, vim lawv tsuas tuaj yeem ua haujlwm tsis muaj txiaj ntsig. barrage hluav taws nrog kho lub hom phiaj ntawm qhov chaw tawg. Ib qho ntxiv, thaum tawg, cov foob pob tawg tuaj yeem tsoo cov yeeb ncuab dav hlau hauv qhov chaw nqaim, uas feem ntau txo qis kev ua haujlwm ntawm kev tua. Nyob rau hauv tag nrho, muaj txog ib puas lub qub 75 thiab 76 mm phom hauv Finland. Feem ntau ntawm lawv tau sau tawm tam sim tom qab Kev Tsov Rog Thoob Ntiaj Teb Zaum Ob xaus.
Xyoo 1927, Finland xaj kom 76mm Bofors M / 27 phom tiv thaiv dav hlau. Qhov sib txawv tseem ceeb yog kev siv 76, 2 mm projectile los ntawm Lavxias "peb-nti". Nyob rau hauv tag nrho, Finns yuav 12 rab phom, npaj tshwj xeeb rau kev teeb tsa hauv cov haujlwm ruaj khov ntawm ntug dej hiav txwv.
Nrog qhov pib nrawm ntawm lub foob pob tawg ntawm 750 m / s, thaj tsam ntawm kev puas tsuaj ntawm huab cua lub hom phiaj yog 6000 meters. Tus nqi hluav taws kub txog 12 rds / min. Ntawd yog, raws li nws tus yam ntxwv, rab phom tiv thaiv dav hlau Swedish tsis txawv ntawm 76 hli Cov phom loj. Nyob rau xyoo 30s lig, cov tawg tawg tawg nrog lub fuse nyob deb tau tsim rau 76 hli phom tiv thaiv dav hlau, tab sis qhov ua tau zoo ntawm kev tua tsis tau nce ntau, txij li qhov hluav taws kub, raws li txoj cai, tau ua los ntawm qhov muag, yam tsis tau siv lub tshuab tshawb nrhiav.
Ib qho kev hloov pauv cuam tshuam, 76mm Bofors M / 28, tau rub. Plaub rab phom tau yuav hauv xyoo 1928 thiab siv feem ntau yog rau kev qhia paub. Tsis ntev ua ntej kev sib tsoo nrog Soviet Union hauv Sweden, ua ke nrog lwm cov phom, lawv tau txais Bofors Ab tiv thaiv dav hlau tua hluav taws, uas ua rau kom muaj txiaj ntsig zoo ntawm kev tua hluav taws. Tsuas yog lub dav hlau tiv thaiv lub dav hlau nrog 76mm Bofors M / 28 hom phom tau siv hauv Helsinki tiv thaiv huab cua kom txog rau thaum lub caij ntuj sov xyoo 1944. Tsis tas li hauv kev tiv thaiv huab cua Finnish muaj tsawg tus rub 76mm Bofors M / 29 phom, sib txawv me ntsis hauv cov ntsiab lus los ntawm tus qauv yav dhau los. Twb tau tom qab pib kev tawm tsam huab cua Soviet, tau hloov kho 75mm Bofors M / 30 tau pom. Nws ntseeg tias cov phom no, uas tiv thaiv lub nroog Helsinki, tau muab los ntawm cov tub rog Swedish nrog rau cov neeg ua haujlwm, thiab tom qab qhov kawg ntawm tsov rog lawv rov los rau lawv teb chaws.
Xyoo 1936, nrog rau Bristol Bulldog Mk. IVA, Finland tau txais 12 Askiv 76 ITK / 34 Vickers. Hauv tebchaws Askiv cov phom no hu ua 76.2mm Q. F. 3-in 20cwt phom tiv thaiv dav hlau. Thaum xub thawj, rab phom tau siv rau kev tua ntawm lub hom phiaj huab cua; nyob rau nruab nrab -30s, cov tawg tawg tawg nrog lub raj nyob deb tau qhia rau hauv cov mos txwv. Kev tswj hluav taws ntawm lub dav hlau tiv thaiv lub dav hlau tau siv PUAZO. Lub foob pob tawg tawg hnyav txog 5.7 kg, tawm hauv lub thoob ntawm qhov nrawm ntawm 610 m / s, muaj qhov siab txog ntawm 5000 m. Tus nqi ntawm rab phom yog 12 rds / min.
Cov phom tiv thaiv dav hlau, tsim los ntawm cov tub rog 76-mm dav phom ntawm 1916 tus qauv, tau nrov ntawm cov tub rog. Nws qhov zoo yog qhov yooj yim thiab ntseeg tau. Tab sis los ntawm xyoo 1939, txawm hais tias muaj kev pabcuam zoo thiab ua haujlwm zoo, Askiv peb-nti rab phom tiv thaiv dav hlau tsis tau raws li qhov xav tau niaj hnub no. Ua ntej tshaj plaws, ntawm qhov ntau thiab qhov siab. Nyob rau lub caij ntuj no, Vickers M / 34 lub dav hlau tiv thaiv lub roj teeb tiv thaiv cov khoom siv feem ntau khov thiab tsis kam ua haujlwm. Yog li ntawd, lawv yuav tsum tau nruab nrog hluav taws xob cua sov.
Txij li tom qab xyoo 1942 cov khoom lag luam hauv tebchaws Askiv tau ploj mus, lawv tau siv 76mm Bofors M / 27 mos txwv rau tua. installation nyob rau hauv txoj hauj lwm nyob ruaj ruaj. Cov phom no, tom qab kho dua tshiab ntawm cov cuab yeej taw qhia, tuaj yeem tua ntawm cov ntaub ntawv ntawm lub hom phiaj phom. Txawm hais tias pom tau tias muaj qhov qub, 76 mm Askiv ua cov phom loj tau dhau los ua lub siab ntev: raws li txoj cai, lawv tau ua haujlwm nrog tiv thaiv ntug dej hiav txwv txog rau thaum nruab nrab-80s ntawm lub xyoo pua xeem.
Thaum Lub Ob Hlis 1940, 12 76-mm phom tiv thaiv dav hlau 76 ITC / 16-35 Br. Cov phom tau tsim xyoo 1935 los ntawm Breda cov kws tshaj lij ntawm lub hauv paus ntawm 76 mm Breda qauv 1916 cov tub rog.
Cov phom loj nrog lub cev hnyav nyob rau hauv kev sib ntaus ntawm 2680 kg tuaj yeem tua hluav taws ntawm cov hom phiaj ya ntawm qhov siab ntawm 5900 meters thiab thaj tsam ntawm 7800 meters. Kev faib ua feem ntawm qhov hnyav ntawm 5, 65 kg, tawm ntawm lub thoob ntawm qhov ceev ntawm 690 m / s. Cov phom tiv thaiv dav hlau ntawm xyoo 1935 tus qauv tau txais qub qub tsis siv lub ntsia liaj qhov rooj los ntawm rab phom tub rog, uas yuav tsum tau muab xauv tus kheej tom qab xa lub plhaub. Vim li no, qhov ua tau zoo ntawm qhov hluav taws kub tsis tshaj 10 rds / min. Tom qab xyoo 1944, txhua rab phom ntawm hom no tau pauv mus rau cov phom loj ntawm ntug dej hiav txwv.
Feem ntau, cov phom loj tiv thaiv dav hlau Finnish, tsim los tiv thaiv kev ya dav hlau ntawm nruab nrab thiab qhov siab, tsis tau raws li qhov xav tau niaj hnub no. Qhov xwm txheej zoo dua nrog rab phom tiv thaiv dav hlau me me. Tom qab kev puas tsuaj ntawm Lavxias Lub Tebchaws, ntau dua 60 47 hli Hotchkiss cov phom tsis siv neeg (Lub npe Finnish 47/40 H) thiab 57 mm Nordenfelt (57/48 No.) tseem nyob hauv Finland.

Thawj 30 ntawm 134 20mm phom xaj thaum Lub Kaum Hli 1939 tuaj txog ob peb lub lis piam ua ntej Tsov Rog Zaum Ob. Tom qab muaj kev tawm tsam kev tawm tsam, kev xa khoom ncaj qha los ntawm lub teb chaws Yelemees tau nres, tab sis lawv tau hla hla Sweden. Tom qab qhov kev sib cav xaus, tag nrho cov kev txwv tau raug tshem tawm. Hauv ob qhov kev tsov kev rog nrog Soviet Union, 163 German MZA 2, 0 cm Flak 30 thiab 2, 0 cm Flak 38 tau koom nrog. Lawv qhov kev suav suav tau tshaj tawm tias yeej 104 lub dav hlau Soviet thaum lub caij Tsov Rog Tsov Rog, tab sis cov duab no yeej ntau zaus dhau lawm. Oddly txaus, Finns nyiam thaum ntxov 2.0 cm Flak 30 nrog tus nqi hluav taws tsawg dua. Lawv suav tias rab phom tiv thaiv lub dav hlau no muaj tseeb dua thiab ruaj khov dua li 2.0 cm Flak 38. Cov mos txwv rau cov tub rog German ua cov phom tiv thaiv dav hlau tau muab los ntawm lub tebchaws Yelemes.
Thaum Tsov Rog Zaum Kawg, Cov tub rog Finnish muaj coob tus tiv thaiv dav hlau tua phom tshuab. Cov no feem ntau yog rab phom tshuab Maxim yoog rau kev tua ntawm lub hom phiaj huab cua. ZPU rab phom caliber ItKk 7, 62/31 VKT tsim nyog tau hais tshwj xeeb
Cov phom tiv thaiv dav hlau ntxaib tau tsim los ntawm tus kws paub phom Finnish Aimo Lahti los ntawm M / 32-33 tshuab rab phom, uas nyeg muaj ntau yam sib xws nrog rab phom tshuab Russia ntawm xyoo 1910 tus qauv. Cov phom tshuab siv tib daim cartridge 7, 62 × 53 mm R.
Cov txheej txheem, ZPU 7, 62 ItKk / 31 VKT yog ob rab phom Maxim tshuab nrog rau tag nrho cov nqi hluav taws kub ntawm 1800 rds / min. Txhawm rau txo tus naj npawb qeeb thiab nce tus nqi hluav taws, daim kab xev daim kab xev tau hloov pauv los ntawm cov hlau txuas kab xev nrog lub peev xwm ntawm ob lub thawv ntawm 500 ncig. Lwm qhov sib txawv yog lub tshuab cua txias ua kom txias txias, uas txo qis qhov hnyav ntawm chav tsev thiab ua kom yooj yim siv thaum lub caij ntuj no. Nws tau ntseeg tias nws muaj peev xwm tua 250 qhov kev sib tw puag ncig hauv qhov tawg ntev ntawm txhua lub thoob tsis muaj cua sov. Kev teeb tsa hnyav 104 kg tau ua haujlwm los ntawm cov neeg coob ntawm 6 tus neeg. Lub hauv paus rau rab phom tshuab yog qhov loj heev, ruaj khov conical bollard nrog qhov siab ntawm 135 cm. Kev tua tau zoo ntawm huab cua lub hom phiaj yog 600 meters.
Coj mus rau hauv tus account kev sib ntaus sib tua tau txais thaum lub caij Tsov Rog Tsov Rog, lub tshuab rab phom niaj hnub nce 7, 62 ItKk / 31-40 VKT tau tsim nrog cov khoom siv sab nraub qaum, pom qhov tshiab, lub qhov ncauj nres thiab ua kom txias dua. Raws li cov kws sau keeb kwm Finnish, ua khub ZPU 7, 62 ItKk / 31-40, vim nws qhov hnyav me me thiab qhov ntev, yog riam phom zoo dua li Soviet M4 plaub fab ntawm 1931 tus qauv. Hauv tag nrho, 507 ZPUs tau tsim los ntawm 1933 txog 1944. Hauv kev ua haujlwm, nws yog kev ntseeg tau zoo thiab muaj txiaj ntsig zoo los tsoo lub hom phiaj huab cua qis. Txawm li cas los xij, nyob hauv ib nrab ntawm kev ua tsov rog, kev ua haujlwm ntawm kev siv phom-rab phom-rab phom-phom loj tau poob qis. Txawm li cas los xij, ZPU 7, 62 ItKk / 31-40 VKT tau khaws cia txog thaum 1986. Thaum lub sijhawm tshem tawm, muaj 467 qhov kev pabcuam tau teeb tsa, suav nrog 41 lub txim 7, 62 ItKk / 31 VKT thaum Tsov Rog Zaum Kawg.
Ib yam li hauv cov dav hlau tua rog, thaj av tiv thaiv Finnish huab cua tiv thaiv thaum Tsov Rog Tsov Rog vam khom cov khoom siv thiab riam phom txawv teb chaws. Cov npe loj ntawm cov qauv sib txawv ua rau muab cov mos txwv tsis sib pauv thiab kho teeb meem. Nws yog qhov tsim nyog tias tus naj npawb ntawm 75-76 mm phom tiv thaiv lub dav hlau tau pom meej tias tsis txaus, thiab feem ntau ntawm lawv yog hom qub. Hauv Finnish huab cua tiv thaiv kab ke, muaj qhov tsis ncaj ncees rau ZPU thiab MZA, uas xav txog lub hom phiaj los npog lawv cov tub rog los ntawm kev tawm tsam dav hlau ua haujlwm ntawm qhov siab qis, tab sis ntau lub tswv yim tsis zoo tiv thaiv kev foob pob. Ib qho ntawm kev sim daws qhov xwm txheej yog tsim cov roj teeb tiv thaiv dav hlau ntawm cov tsheb ciav hlau. Lawv tau sim npog cov tsheb thauj mus los thiab chaw nres nkoj.
Lwm qhov tsis muaj zog ntawm kev tiv thaiv huab cua yog qhov tsis txaus ntawm cov cuab yeej tshawb pom suab nrov thiab tiv thaiv lub dav hlau tshawb nrhiav. Yog li, thaum Lub Kaum Ob Hlis 1939, cov chaw tiv thaiv huab cua tsuas muaj 8 lub chaw hu nkauj, 8 lub teeb tshawb nrhiav thiab 20 lub chaw soj ntsuam huab cua, nruab nrog kev sib txuas lus. Tom qab pib muaj kev sib cav sib ceg, tus naj npawb ntawm VNOS tshaj tawm ib puag ncig cov chaw tseem ceeb tau nce ntau zaus ntau dua. Finland tau muab faib ua 52 thaj chaw soj ntsuam huab cua, thiab tus naj npawb ntawm cov lus soj ntsuam tshaj 600. Txhua qhov tshaj tawm muaj xov tooj lossis xov tooj cua sib txuas lus. Qhov no, tau kawg, pab tau ceeb toom rau cov pej xeem txog kev tawm tsam huab cua, tab sis tsis tuaj yeem tiv thaiv lawv. Raws li cov peev txheej hauv Finnish, thaj av tiv thaiv Finnish huab cua tiv thaiv thaum Tsov Rog Tsov Rog tau tua los ntawm 300 txog 400 tus yeeb ncuab dav hlau. Hauv qhov tseeb, kev ua tiav ntawm cov phom tua phom loj yog 4-5 zaug tsawg dua. Txawm li cas los xij, cov phom loj tiv thaiv dav hlau Finnish tsis muaj feem cuam tshuam rau kev ua phem thiab tsis tuaj yeem tiv thaiv cov khoom tiv thaiv los ntawm kev foob pob.
