Structure for missiles and solid rocket motors, vertically integrated and built at full rate.
The munitions industrial base is short of qualified structure. Janicki supplies it: solid rocket motor cases and skirts for tactical missiles and ICBMs; cruise missile fuselages, fins, wings and control surfaces. Metal and composite, in-house, in the United States.

Vertical integration
Forging to finished case, in-house.
Flow forming, machining, EB welding, heat treatment and composites are all in-house, so a case does not leave Janicki's quality system between raw stock and delivery.
Flow forming
Thin-wall, high-strength motor cases flow formed to near-net wall, with the grain structure and wall uniformity a pressure vessel demands.
Machining
Turning and 5-axis milling of cases, skirts, adapters, domes and closures in steel, titanium and aluminum.
Electron beam welding
Deep, narrow, low-distortion welds for case-to-skirt, dome and closure joints, in vacuum, with weld schedules developed and qualified in-house.
Heat treatment
In-house austenitize, quench, temper and age cycles for motor-case alloys, with furnace surveys and pyrometry to aerospace standards.
Full composites capability
Composite cases, fuselages, fins, wings and control surfaces: hand layup, fiber placement, autoclave and out-of-autoclave cure, resin infusion, trim and drill, bonding and assembly — Nadcap-accredited.
Inspection and test
Nadcap NDT, laser-tracker and CMM metrology, and proof and leak testing on the same floor, with full traceability by serial number.
Structure at rate
Cases, airframes and control surfaces, at rate.
Programs are usually gated by whether anyone can produce qualified structure at the quantity and cadence required. That is the capacity Janicki is building.
Solid rocket motor structure
Composite and metallic structure for tactical and strategic solid rocket motors: cases, skirts and adapters, including ICBM parts. Metallic cases are flow formed, machined, EB welded and heat treated in-house; composite cases are laid up, cured, trimmed and inspected on the same floor.
Janicki's role is structural. All energetic material handling stays with the customer or their qualified loading facility.
Cruise missile fuselages
Complete fuselage and airframe structure, in aluminum and composite, for standoff weapons and cruise missiles, delivered with internal structure, fittings and provisions installed, fully stuffed, at missile quantities.
Fins, wings and control surfaces
Fins, deployable and fixed wings, canards and control surfaces: thin, highly loaded composite structure where weight, repeatability and interface tolerance all matter, on production tooling.
Rate production and surge
Hamilton and Layton run multiple tool sets and qualified processes, so a program can scale without requalifying the part.
