With a stealthy fighter you could make an attack on another aircraft
without alerting them, except for the IR signature of the missile's
rocket or ramjet engine.

Is anybody planning a stealth AAM that uses a turbojet?

Given its speed and short time of flight, an IR AAM is already stealthy except
for the exhaust plume. A smokeless exhaust would help "complete" the stealth.
OTOH, if the exhaust plume is your first and only indicator of the missile
launch, you may well be too late for evasion...

A turbojet engine would make the missile slower, bigger, heavier, and less
maneuverable.
