U-Chinook uphila phakade?
Ngokwezinhlelo ezivela ku-Boeing kanye noMnyango Wezokuvikela wase-US eminyakeni embalwa edlule, i-CH-47F Block II bekufanele ibe insika yemikhumbi yezokuthutha yezempi yase-US kuze kube okungenani maphakathi naleli khulu leminyaka.
Ngomhla zingama-28 kuNdasa, indiza enophephela emhlane yokuqala ethwala kanzima, i-Boeing CH-47F Chinook Block II, yasuka esikhumulweni sezindiza senkampani ePhiladelphia ngendiza yayo yokuqala, eyayizoba inkunzimalanga yeButho LaseMelika kanye nabalingani kuze kube okungenani ngeminyaka yawo-60. . Ngaphandle uma kunjalo, uhlelo lokuthuthuka nokukhiqizwa kwalo ngobuningi lwehliswa kancane futhi lunqunyelwe izinqumo zosopolitiki, okuvame ukwenzeka eqinisweni laseMelika muva nje.
Ngemva kochungechunge lokuhlolwa kokuqala, imoto kufanele ilethwe endaweni yokuhlola yefekthri e-Mesa, e-Arizona, lapho inqubo yocwaningo nentuthuko izoqhubeka, okuhlanganisa nokubamba iqhaza kwabamele uMnyango Wezokuvikela. Ezinye izindiza ezinophephela emhlane ezintathu zizokwengezwa ekuhlolweni ezinyangeni ezizayo, okuhlanganisa neyodwa esesilinganisweni sokusekela amabutho akhethekile.
I-MN-47G. Ngokusho kwezinhlelo zamanje, ukukhiqizwa kokuqala kwe-Block II rotorcraft kufanele kufake isevisi ku-2023 futhi kuzoba inguqulo ekhethekile ye-MH-47G. Ngokuphawulekayo, indiza yokuqala yenziwa kusetshenziswa ama-rotor blades akudala kunama-ACRB athuthukile. Ezokugcina, u-Boeing asebenze iminyaka eminingana, zenzelwe ukwandisa amandla okusebenza we-rotorcraft - kuphela ngenxa yabo, umthamo womthwalo ezimweni ezishisayo neziphezulu kufanele zikhuphuke ngo-700-900 kg.
Esinye sezizathu zomsebenzi wokugunyazwa kwe-Block II kwaba ukungenzeki kokukhwezwa kwe-JLTV ngaphansi kwe-CH-47F Block I fuselage, lapho i-HMMWV ingumkhawulo womthamo womthwalo.
Uhlelo lokwakhiwa kwendiza enophephela emhlane ye-CH-47F Chinook lwaqala ngeminyaka yama-90s, i-prototype yokuqala yandiza ngo-2001, futhi ukulethwa kokukhiqiza kwaqala ngo-2006.
ing ilethe ama-rotorcraft angaphezu kuka-500 ale nguqulo ku-US Army kanye ne-US Special Operations Command (ezinye zazo ezidalwe ngokwenza kabusha i-CH-47D nokuphuma kwayo) kanye neqembu elikhulayo labasebenzisi abathumela ngaphandle. Njengamanje, iqembu labo lihlanganisa amazwe angu-12 avela emhlabeni wonke, a-ode amakhophi angaba ngu-160 (futhi kulokhu, amanye awo akhiwa ngokwakha kabusha i-CH-47D - lena yindlela abaseSpain namaDashi abayithatha. ). Amathuba okuthengisa okuningi ahlala ephezulu njengoba i-Boeing yenza imizamo yokuthengisa ejulile yokuthengisa izindiza ezinophephela emhlane kubasebenzisi abakhona be-Chinook, kanye nasemazweni lapho i-CH-47 ingakaze isetshenziswe khona ngaphambili. I-Israel ne-Germany (i-Chinooki ayisetshenziswa kulawa mazwe, futhi kuzo zombili izimo i-CH-47F incintisana nendiza enophephela emhlane i-Sikorsky CH-53K King Stallion), iGreece ne-Indonesia zibhekwa njengosonkontileka abangase bathembise. I-Boeing njengamanje ilinganisela isidingo somhlaba wonke sokuthi okungenani ama-Chinook ayi-150 adayiswe ngo-2022, kodwa yizinkontileka kuphela esezinikeziwe ezizogcina umugqa wokuhlanganisa usebenza kuze kube sekupheleni kuka-2021. Inkontileka yeminyaka eminingi yaphothulwa phakathi koMnyango Wezokuvikela kanye ne-Boeing ngoJulayi 2018 ihlanganisa
inani lezinketho zokuthekelisa zezindiza ezinophephela emhlane ze-CH-47F Block I nge-FMS, ezingakhiqizwa ekupheleni kwe-2022, kodwa abekho abathengi bazo kuze kube manje. Lokhu kungase kube inkinga kumkhiqizi, njengoba kungase kusho ukugcinwa komugqa wokuhlanganisa kuze kube yilapho uhlelo lwe-Block II luxhaswa ngokugcwele kanye nenkontileka yesikhathi eside yokuguqula cishe ama-542 CH-47F/Gs amasosha ase-US abe kuleli zinga. Le misebenzi izokwenziwa ngo-2023–2040, futhi amakhasimende angase athumele kwamanye amazwe kufanele engezwe kule nombolo.
Kungani i-Block II yethulwa? Lona umphumela wezifundo ezifundwe ezingxabanweni zezikhali nemisebenzi yokusiza abantu lapho amabutho ase-US aye ahileleka khona kuleli khulu leminyaka. Izibalo ezivela eMnyangweni Wezokuvikela azinakulinganiswa - ngokwesilinganiso, minyaka yonke isisindo sezindiza ezinophephela emhlane ze-CH-47 sikhula cishe ngama-45 kg. Lokhu-ke kubangela ukuncipha komthamo wokuthwala, ngakho-ke, amandla okuthutha impahla nabantu. Ngaphezu kwalokho, isisindo semishini ethuthwa amasosha ngomoya siyanda. Ukwengeza, izindaba zezomnotho ziyizici ezibalulekile - izindleko zokusebenza ezikhuphukile kanye nezikhathi ezikhulayo zokuhlola nezokugcina, ikakhulukazi phakathi nemisebenzi yohambo lwesikhathi eside (isibonelo, e-Afghanistan noma e-Iraq). Ukuhlaziywa kwazo zonke lezi zindaba kwenze iPentagon igunyaze (ngakho-ke, ngokuyinhloko isikhwama) umsebenzi okuhloswe ngawo ukuthuthukisa inguqulo entsha ye-US Army workhorse kanye nemoto ebalulekile ye-SOCOM, i.e. I-CH-47F Chinook Block II. Izimali zokuqala zadluliselwa ngoNdasa wezi-2013. UBoeing wabe esethola u-$17,9 million. Inkontileka enkulu yasayinwa ngoJulayi 27, 2018 futhi ifinyelela ku-276,6 wezigidi zamadola aseMelika. I-U.S. Special Operations Command iphinde yengeza enye imali eyizigidi ezingu-29 zamaRandi ehlobo eledlule.
Iziqubulo zalolu hlelo zithi “Ukuthwala amandla kanye nokwehliswa kwezindleko zokusebenza.” Kuze kube manje, abaklami be-Boeing, ngokuvumelana noMnyango Wezokuvikela, banqume ukwenza isigaba esilandelayo sokuhlanganiswa kwemishini phakathi kwe-CH-47F "eyisisekelo" ne-MH-47G "ekhethekile", kanye nokusebenzisa ulwazi lwaseCanada. Okokuqala, sikhuluma ngesidingo sokwandisa umthamo wokuthwala ezindaweni ezishisayo neziphezulu. U-Boeing uthi le nguqulo entsha izokwandisa umthamo wokulayisha cishe ngamakhilogremu angu-2000, okudlula kude izidingo zoMnyango Wezokuvikela zamakhilogremu angu-900, kuhlanganise nama-700 ezindaweni eziphakeme, ezishisayo.
