The turborocket design offers a mixture of benefits with drawbacks.
2.
For the same mass of fuel as a rocket motor, the overall output of the air turborocket is much higher.
3.
In applications which stay relatively in the atmosphere and require longer durations of lower thrust over a specific speed range the air turborocket can have a weight advantage over the standard solid fuel rocket motor.
4.
The air-turborocket fills a niche ( in terms of cost, reliability, ruggedness, and duration of thrust ) between the solid-fuel rocket motor and gas turbine engine for missile applications.
