Tub Rog Asmeskas Pab Tub Yees Duab
Ob peb lub lis piam tom qab thawj cov lus xaiv tau tshaj tawm tias Ukrainian air Force yuav tau txais satellite-guided glide-bombs los ntawm Tebchaws Meskas, ib tus neeg ua haujlwm hauv tebchaws Meskas tau lees paub tias, yog, qee qhov kev sib koom tes ncaj qha sib ntaus sib tua tau tuaj txog hauv Ukraine.
"Lawv muaj txaus los ua ob peb qhov kev tawm tsam," US Air Force General James Hecker, tus thawj coj ntawm US Air Forces hauv Tebchaws Europe, qhia reporters kuj muaj Tsov RogJoseph Trevithick lub lim tiam dhau los.
Nrog rau lawv qhov siab tshaj plaws 45 mais, cov foob pob yog lub peev xwm tshiab muaj zog. Tshwj xeeb yog hais tias cov Ukrainians kuj tau txais qhov zoo tshaj plaws fuzes. Nrog rau xyoo 1970s-vintage DSU-33, Asmeskas qhov sib thooj sib xws.
Bombs tsis tsim sib npaug. Lub casing tseem ceeb. Cov explosives mix teeb meem. Lub fuze tseem ceeb, ib yam nkaus-a ntau.
Qhov yooj yim fuze yog ib qho cuam tshuam fuze nrog ib tus pin firing lossis crush keyboards. Thaum lub foob pob tsoo hauv av, qhov cuam tshuam nias tus pin rau hauv lub detonator lossis compacts cov keyboards. Tawg.
Kev ncua sij hawm fuze tos me ntsis tom qab cuam tshuam kom lub foob pob faus nws tus kheej mus rau hauv av ua ntej tawg. Tsuas yog qhov uas yuav rhuav tshem lub qhov, qhov tsua lossis hauv av bunker.
Tom qab ntawd muaj qhov sib thooj fuze. Ua tsaug rau ib qho me me radar lossis lwm yam sensor, lub fuze paub thaum nws yog qhov siab tshaj hauv av - thiab ua rau lub foob pob tawg hauv nruab nrab huab cua. Lub foob pob nyob sib ze yog txoj hauv kev zoo tshaj plaws rau cov tub rog uas muaj kuab lom nrog cov kab mob tuag taus, lossis nthuav dav thaj tsam moj tej tawg kom thiaj li ua kom lub teeb ci ntsa iab.
"Ib qho airburst fuze ntawm cov pa phem tuaj yeem ua rau nws thaj chaw muaj txiaj ntsig txog li 100 feem pua," Geneva International Center for Humanitarian Demining sau tseg.
Cov nyhuv no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau sab hnub tuaj Ukraine, qhov chaw sib ntaus sib tua phem tshaj plaws nyob rau hauv lub ruins ntawm cov nroog thiab cov nroog - thiab qhov chaw uas cov tsev tso tseg ua haujlwm raws li kev sib ntaus sib tua, cov lus txib thiab bivouacs.
Nyob rau hauv ib puag ncig no, 500-phaus JDAM-Ntev Range nrog DSU-33 radar fuze, teem kom tawg 20 ko taw saum av, yuav zoo li lub pob tawg.
Ukrainian fighter pilots tuaj yeem ya qis kom tsis txhob muaj kev tiv thaiv Lavxias huab cua, nce siab thaum lawv mus txog ntawm kab pem hauv ntej thiab lob lawv JDAM-ERs ntawm lub kaum sab xis siab. Lub foob pob tis tawm thiab lawv glide rau mais ua ntej arcing down thiab tawg 20 ko taw hla ib co plhaub-pocked ru tsev.
Nws yog lub luag haujlwm txaus ntshai rau tus tsav dav hlau tawm tsam - tab sis cov txiaj ntsig, rau cov tub rog phooj ywg hauv av, tuaj yeem tsim nyog rau kev pheej hmoo. Hecker hais tias "Muaj cov tswv yim uas koj tuaj yeem mus rau qhov qis thiab ua qee yam ... thiab rov qab los," Hecker hais.
Kom meej meej, tsis muaj pov thawj tias cov Ukrainians tau txais DSU-33s rau lawv JDAMs.
Txawm li cas los xij, tsis muaj laj thawj lawv yuav tsum tsis ua. Cov tuam txhab Asmeskas tau tsim ntau pua txhiab tus fuzes ntau xyoo lawm. Dave Liberatore, Northrop Grumman's DSU-33 program manager, "DSU-40 tau yog ib qho kev ua tau zoo tshaj plaws ntawm cov phom fuzing / sensor program hauv 33 xyoo dhau los," hais hauv 2019.
US Air Force hauv nws daim phiaj siv nyiaj 2023 tab tom thov $ 120 lab rau, ntawm lwm yam, them rau kev txhim kho version ntawm DSU-33.
