What Is Happening With The Mitsubishi SpaceJet?

The Mitsubishi SpaceJet has been a long time coming. With orders totaling 213 firm and 194 options, many of which were placed as long ago as 2008, you’d think we’d be seeing this aircraft pulling up at regional stands all over the world by now. But it has yet to be delivered to its launch customers. Here’s what’s going on now with the MRJ, now known as the SpaceJet.

Back in mid-June, Mitsubishi announced that they would rename their Mitsubishi Regional Jet (or MRJ) to the SpaceJet. This would initially encompass two models; the existing MRJ 90 which would be renamed the SpaceJet M90, and the newly unveiled and slightly smaller SpaceJet M100.

The M100 was an evolution of a previous Mitsubishi concept dubbed the MRJ70. This was an aircraft specifically designed for the US market, to overcome specifics of the pilot scope clause that limit the size and number of aircraft flown. The M100 was to slot into the 65-76 seat, three class marketplace, and should have been a shoo-in for US regional fleet renewal.


And yet, we haven’t seen any operating in the US or otherwise, so what’s going on with the SpaceJet?


A brief history of the SpaceJet

The concept of the SpaceJet has its roots way back in 2003, when the Japanese government launched a five year research program to develop an indigenous regional jet. The program was led by Mitsubishi Heavy Industries (MHI).

The first concept was unveiled at Paris Air Show in 2007, with the program officially kicked off the following year at Farnborough. At the time, the Mitsubishi Regional Jet program, as it was then known, announced an initial order for 25 jets from All Nippon Airways (ANA) with a target launch date of 2013.

However, that launch date was to prove to be somewhat optimistic. Delay after delay beset the program, pushing back first flight and subsequent launch time after time. Finally, the maiden flight of the MRJ90 took place in the 11th November 2015. At that point, Mitsubishi announced a new launch date of mid 2018 for the jet, but again that was to prove untenable.

In January 2017, the launch was pushed back to mid-2020. Many of these delays were caused by failure to document work done for certification purposes. At the last count, the program has cost Mitsubishi 350bn yen ($3.17bn). Reuters suggests that it would take sales of 800 models of the aircraft at least for the program to break even, suggesting that it probably never will.

So where are we now?

The M90 SpaceJet has entered the final stage of flight testing, and will, with any luck, be delivered by summer 2020 to its launch customer, ANA. This represents the culmination of a 15 year odyssey to get an aircraft certified. Chances are Mitsubishi have learned a lot from their experience, which can hopefully now be applied to their second model – the SpaceJet M100.

Earlier this year, MHI snagged a partnership with Triumph to undertake some modifications to the M100 line. Previously, the aircraft was too small for a scope clause compliant aircraft, where the M90 was too big. Triumph helped them expand the fuselage by two feet without any weight penalty, which has allowed them to get the necessary 76 seats into the cabin.

As such, this aircraft could be a key contender for the US regional fleet renewal, but they need to stick to their timelines. With Embraer already pushing the E-Jet as a new regional solution, Mitsubishi will need to be quicker getting this one off the ground if they want to bag their share of the market.

However, the jet looks promising, and apparently at least one carrier thinks so too. An undisclosed US airline signed an MoU for 15 of the type at this year’s Paris Air Show, with deliveries slated to begin in 2024. If Mitsubishi can deliver on time, we could see the SpaceJet M100 appearing in many North American fleets over the next decade.

I’m surprised this thing is taking this long. I wonder how many airlines will be scared off by the delays. This is a world where airlines didn’t trust the bombardier c series until it was sold to Airbus. Now they look like a mob at Walmart on black Friday trying to get their orders in. I could see this thing having a similar fate.


I hope the Spacejet comes online soon despite the constant delays. Mitsubishi may be new or rusty at building airplanes, but they are a long-standing, well-respected company. The Spacejet, and similarly the E jets could potentially fill an important niche for the holiday travel market, which is to fly seasonal service in winter from smaller cities in North America and Europe to warm vacation destinations in the Caribbean, islands in the Atlantic and Mediterranean.


After the 737-Max debacle I wonder whether the arduous certification journey might be recast as an asset in the spirit of “thorough due diligence” and seen as a vote of confidence by some airlines. …when it finally gets to market of course.

How does it take Mitsubishi 17 years to develop an aircraft that is essentially a carbon copy of the Embraer E series. Unless it offers something substantially different from the Embraer E2’s or the Airbus A220 series – I doubt that it will be successful.


Mitsubishi assumed that acquiring aircraft development knowledge and skills from foreigners will shorten their route to development of their own Japanese aerospace industry. Great concept, except little did they know that that the bunch of incompetent engineering mercenaries they hired from failing Bombardier to lead the program will put them on the same failing track that brought Bombardier down. Combine this with selecting second, third and fourth grade foreign suppliers and an unexplained extreme passive follower attitude of the Japanese team, led to the failing endeavor of the MRJ. As a former employee, I have been watching the failing pattern… Read more »
