Edit: With a bit of Wikipedia diving, it looks like Mitsubishi has made a ton of post WWII aircraft, ranging from jets to helicopters, some developed independently and some with help from other companies. The X-2 looks pretty interesting. I love the red, white, blue, and black paintjob. It looks like something out of a comic or classic anime show.
Meanwhile, Mitsubishi is throwing their hat into the ring. They've got orders and have done for eight years but they ain't delivering, from what I understand.
From Wikipedia's article . . .
On 21 May 2017, Iran canceled its plans to buy Mitsubishi's Regional Jet (MRJ) from the Japanese company. Inability to set a delivery timeline for ordered aircraft and lack of testing were cited as their main reasons.
I remember in the '90s, Mitsubishi used to be everywhere I looked. Not just cars, but televisions and such, air conditioners, commercial trucks. For some reason, their red three diamond symbol always stood out to me and I'd stumble on it in the most random of places at the most random of times. Now, with the exception of their cars and the occasional FUSO on the road, I don't see them anymore. I remember vaguely, very vaguely, a commercial on TV for a Mitsubishi air conditioner a few years ago, and that's it. Which is weird, because they still do an ass-ton of stuff according to their Wikipedia article, but their American presence outside of transportation seems to be near zero.
As an aside, I find it interesting that both Mitsubishi and Fuji Heavy Industries both have a history of partnering with American companies to build their aircraft.
