The long, slow death of Mitsubishi’s SpaceJet

Feb. 9, 2023, © Leeham News:

Mitsubishi Heavy Industry’s (MHI) announcement this week that it finally killed the SpaceJet program is hardly new. This was apparent as far back as January 2020 when all the Canadian and American leadership at Mitsubishi Aircraft Corp (MITAC) was unceremoniously booted out. 

Acquiring the CRJ program
One major consideration as the Western executives worked to save the program identified was the need for a global support system for their regional jet. Creating one from scratch would be an immense task. Talent, locations, infrastructure and not the least time and money were obstacles. So MITAC proposed to MHI that Bombardier’s entire CRJ program and its global support system be acquired. The CRJ itself was already a dead duck. Outclassed by the E-Jet and ignored by Bombardier as its focus shifted to the mainline C Series jet, there was a backlog of perhaps two dozen CRJs. Bombardier already planned to end production. MHI agreed to buy the CRJ global support system for eventual transition to the SpaceJet. The remaining orders for the CRJ came with it. The purchase price was about US$550m, with a targeted closing date of June 1, 2020.

• 一篇文章中提到，美加在加拿大的支線客機龐巴迪失敗以後，拚命扶持日本MRJ，出技術出人才，提供市場，訂購幾百架MRJ -easycity- ♂ (0 bytes) () 06/01/2023 postreply 07:31:19

• 中國的支線客機ARJ21早就成功地進行了商業運營。日本支線客機MRJ都因為技術水平無法支持而失敗，談什麽與C919競爭？ -easycity- ♂ (0 bytes) () 06/01/2023 postreply 07:44:26

• 別逗了,ARJ21不過造了一百架,算給黨掙錢,和西方商業兩碼事,巴西造了幾千架 -BBL123- ♀ (0 bytes) () 06/01/2023 postreply 07:58:49

• 爭論最好根據事實。光是美國的航空公司，就給MRJ下了幾百架初始訂單。當時空客沒有支線客機。歐洲和東南亞，都會是MRJ市場 -easycity- ♂ (0 bytes) () 06/01/2023 postreply 07:40:08

• 商業本來就是競爭的。麵對一個巴西的公司，三菱就連競爭都不敢，那三菱以後還能幹什麽？MRJ失敗，也證明了三菱不能幹客機。 -easycity- ♂ (0 bytes) () 06/01/2023 postreply 07:42:44

• 日本MRJ造好後送FAA評審，被指出九百多項缺陷。為了給日本鼓勁，美加決定把龐巴迪支線客機分部整體並入三菱。三菱還是退縮 -easycity- ♂ (0 bytes) () 06/01/2023 postreply 07:35:03

• ARJ21在各方麵的經驗，尤其是第一次申請適航證的經驗，對C919的成功，都有幫助。C919是中國各行各業飛速發展的成果 -easycity- ♂ (0 bytes) () 06/01/2023 postreply 07:46:36

• 根據維基，開發MRJ的三菱航空株式會社，股東包括三菱，豐田，住友，三井，日本開發銀行。有日本政府直接注資，還有間接支持 -easycity- ♂ (0 bytes) () 06/01/2023 postreply 07:58:40
