McDonnell-Douglas F-15E multirole strike fighter for when subtlety is overrated.
Will break the sound barrier in a vertical climb off the runway, tops out when the engines overheat approaching Mach 3 at altitude.
Handles well at low speeds, gets a bit twitchy as you go faster. Large rudder inputs at excessive speed will put you into a flat spin, just beware. Easy enough to recover if you have the altitude.
I hid a second pair of Panthers inside to get a decent speed out of it. Will pass Mach 1 in level flight at sea-level under normal aspiration. Onboard fuel lasts a little more than 8 minutes at full burn, fit drop tanks if you need to cover distance.
