An American chemical company that in the late 1940's produced solid fuel rocket engines for application to guided missiles such as the JB-2 and the “Navy Loon” both with a 2CS-10000 (T-10) that gave 9600 lbf of thrust using CP-492 fuel leaving dense white smoke.

From Appendix 6: Chemical company that also made rocket engines, perhaps as an evolution of its background in chemistry.

-T-10 engines are already mentioned in the main text. Now we have an image of a battery of 5 of these engines in which the central one stands out.
