I have done this with Mongoose Supplement 6, military vehicles, and made something at TL7 with about the same stats as a modern RL jet fighter. It only cost about a million credits, not sure how that compares to RL currency. Top speed, about 1.65 Mach, Air-to-Air missiles and a Vulcan light autocannon, far less armor than it -could- mount, because trying to keep it realistic. So it's very do-able in that system. I don't know Striker, but I imagine if you look up actual stats on wikipedia, you can get an idea of what sort of values to aim for. For TL7/8 anyhow. Past that, go nuts.
