Do you know what strength, 85,90, 98% (FMC)?
In the 90's I fired a 3.5 KLbF ablative thrust chamber for OSC  with 85%
HTP and Jet-A. It didn't lead to anything.

Yes, HTP/kerosene for the rocket plane. They are also
developing nitrous oxide and propylene thrusters
for satellites (substituting for hydrazine thrusters).
