xob laim II nyob rau hauv qhov kub ntawm kev thuam
Ntau tshaj 100 F-35A Block 2B / 3i tsis haum rau kev sib ntaus sib tua. Lawv hloov kho rau Block 3F / 4 tau suav tias tsis muaj txiaj ntsig.
Tej zaum qhov tseem ceeb tshaj plaws kev txhim kho thiab kev tsim khoom rau Lockheed Martin F-35 Lightning II ntau lub luag haujlwm sib ntaus sib tua dav hlau nyob rau hauv ib nrab ntawm lub xyoo yog kev tshaj tawm tsab ntawv tshaj tawm txog yav tom ntej ntawm ntau tshaj li ib puas daim ntawv xa mus rau US Department of Kev tiv thaiv. Kev tiv thaiv kom txog thaum kawg ntawm kev tshawb fawb thiab kev sim theem.
Lub ntiaj teb kev ua tub rog loj tshaj plaws hauv kev ua tub rog, txawm tias tau txais lub zog, tseem tseem khaws txhua yam kev ntsuam xyuas tseem ceeb ntsig txog kev caij tsheb kauj vab thiab ncua sij hawm. Cov yav tas los qhia ib txhij rau kev siv zog ntawm tag nrho cov kev lag luam thiab cov neeg siv khoom los tsim thiab txais yuav qhov kev cog lus riam phom.
Lub shoals ntawm F-35 program
Txawm hais tias muaj kev tshaj tawm txog kev npaj ua ntej pib los ntawm thawj pab tub rog ntawm US Air Force thiab US Marine Corps, nrog rau kev xa cov tsheb tawm sab nraud Tebchaws Meskas, qhov xwm txheej nrog qhov kev pab cuam yog deb ntawm qhov zoo tagnrho. Thaum lub Cuaj Hlis 18, US Department of Defense tau lees paub tias tus qauv Block 2 thiab Block 3i aircraft tsis npaj txhij. Raws li tau hais tseg lawm: nyob rau hauv qhov xwm txheej sib ntaus sib tua tiag tiag, txhua tus neeg tsav dav hlau ya lub Block 2B variant yuav tsum zam qhov chaw sib ntaus sib tua thiab muaj kev txhawb nqa nyob rau hauv daim ntawv ntawm lwm yam tsheb sib ntaus sib tua. Nyob rau tib lub sijhawm, tus nqi kwv yees ntawm kev hloov pauv / hloov kho lawv mus rau hauv Block 3F / 4 version yuav muaj ntau pua lab nyiaj daus las - peb tab tom tham txog 108 daim ntawv ntawm US Air Force thiab xa cov khoom ntawm F-35B thiab F. -35 C. Lawv cov khoom lag luam nyob rau theem kev tshawb fawb thiab kev loj hlob [tseem hu ua EMD theem, nyob nruab nrab ntawm qhov tseem ceeb ntawm qhov tseem ceeb B thiab lub sijhawm tseem ceeb C, hauv qhov kev tsim khoom loj ntawm cov cuab yeej tsim tshiab, txawm tias LRIP series, tsis raug cai; ib qho kev zam tau ua rau F-35, yog li hu ua. parallelism - ntau lawm yog tseem tsis tu ncua; Raws li txoj cai thiab technically, F-35s ntawm LRIP series tom ntej uas tsim los txog tam sim no yog cov qauv thiab tsis yog (me me) ntau lawm - kwv yees. Qee qhov no tsis cuam tshuam rau software, uas yuav yog "yooj yim" los hloov kho, tab sis rau cov qauv kev hloov pauv uas xav kom lub tshuab xa rov qab mus rau cov chaw tsim khoom rau kev kho dua tshiab.
Yog vim li cas rau qhov kev txav no yog qhov kev txiav txim siab ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv kom nrawm rau txoj haujlwm thiab hloov kho lub US Air Force (parallelism) sai dua. Tib lub sijhawm, qhov no tuaj yeem piav qhia qhov kev yuav khoom me me los ntawm US Navy. Tswb txog qhov kawg ntawm kev tshawb fawb thiab kev loj hlob theem, thiab nrog ntau tus tshiab F / A-18E / F Super Hornets, US Navy tsuas tuaj yeem them taus yuav 28 F-35Cs.
Cov lus nug ntawm yuav ua li cas rau cov tshuab no tau qhib tam sim no - Asmeskas cov kws tshuaj ntsuam tau taw qhia txog peb txoj hauv kev: kev hloov pauv kim rau tam sim no Block 3F tus qauv thiab siv ntxiv rau hauv tsev kawm ntawv thiab cov kab tawm, tsuas yog siv rau kev cob qhia (uas tej zaum yuav cuam tshuam nrog kev cob qhia tom ntej. Cov neeg tsav dav hlau hloov mus rau F-35s tshiab) lossis kev tshem tawm ntxov thiab muab rau cov neeg siv khoom xa tawm raws li qhov hu ua. "Fast track" los ntawm cov peev txheej ntawm Ministry of Defense nrog kev xaiv (ntawm tus nqi ntawm cov neeg siv khoom) hloov kho mus rau tus qauv tshiab. Tau kawg, qhov kev xaiv thib peb yuav yog qhov zoo rau Pentagon thiab Lockheed Martin, uas yuav ua haujlwm nrog kev tsim cov airframes tshiab rau qhov kev pabcuam tus neeg siv khoom loj.
Qhov no tsis yog qhov teeb meem nkaus xwb. Txawm hais tias muaj kev loj hlob ntawm cov tshuab serial, kev qeeb yog cuam tshuam nrog kev nthuav dav ntawm kev tsim kho vaj tse thiab kev cia khoom. Raws li tsab ntawv tshaj tawm Lub Kaum Hli 22 ntawm tsoomfwv, qhov kev ncua sijhawm yog rau xyoo ntev dua li qhov xav tau - lub sijhawm nruab nrab ntawm kev kho qhov hluav taws xob tam sim no yog 172 hnub, ob zaug raws li qhov xav tau. Thaum lub sijhawm Lub Ib Hlis-Lub Yim Hli xyoo no. 22% ntawm cov dav hlau uas muaj los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv tau raug tso tawm vim tsis muaj cov khoom seem. Raws li GAO (lub US sib npaug ntawm NIK), tsis yuav ntau tshaj 2500 F-35s, tab sis tswj kom muaj kev txhawb nqa txaus rau lawv txoj haujlwm yuav yog qhov kev sib tw loj tshaj plaws rau Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv - dhau lub sijhawm ua haujlwm ntawm 60 xyoo. , nws tuaj yeem raug nqi $ 1,1 trillion.
