Current IRST systems vary greatly on performance based on things like target attitude, cloud cover, target speed, air temperature etc. Most importantly its speed is key, most IRST systems ground based, and airborne based have limited ranges, the bomber theoretically would be in and out of the detection zone within seconds, even if it was detected, operational range as to lock on is nearly halved of detection range.
Space borne infrared detection systems which are meant for ICBMs and the like are meant for objects that can be relatively predictable, an aircraft traveling at hypersonic velocities has the ability to easily change course, therefore throwing off the computations that have been established for decades. That is why China developing hypersonic aircraft and missiles is so dangerous, the technology is not entirely there yet for countering them effectively. Essentiall the speed while offering a major disadvantage that could be developed into a suitable detection method over time, the speed combined with heat reduction methods should prove enough for the current times to avoid major issues.
