Document ID: RADR / DOC-10
Version: 1.0.0
Status: Conceptual — mechanical-first prototype plan
Authority for employment detail: Annex F — Employment & breech
Phase 1 proves launcher mechanics and round packaging interfaces before committing to live motor, seeker, or warhead test. Phase 2 (ballistics, static fire, lethality) is explicitly out of scope here.

P1A[Phase_1A_Breech_retention] --> P1B[Phase_1B_Tube_continuity]
P1B --> P1C[Phase_1C_Fire_control_UX]
P1C --> P2[Phase_2_Ballistics_motor]
Proves: Gustav-style flip breech, deadbolt positive lock, rocket retention stop blocks forward motion until interlocks satisfied.
Does not prove: Live motor, seeker track, warhead function, ballistic accuracy.
| Item | Detail |
|---|---|
| Entry | Bench launcher fixture; retention stop hardware; mock tube shoulder |
| Procedure | Cycle breech open/close 50×; attempt forward slide with stop engaged; verify stop releases only when interlock inputs simulated (breech closed + front held + tone) |
| Pass | Deadbolt snap repeatable; stop holds mock tube against ≥ 50 N forward shove when interlocks false; stop releases when all three interlocks true |
| Tolerances | Per Annex F § Prototype tolerance stack — finger intrusion, deadbolt depth, shoulder land |
| Fail | Creep open under shock; stop releases without tone; deadbolt does not seat |
| Artifacts | Video, force log (if available), photos of lock engagement |
| Annex | F § Breech · F § Retention stop |
Proves: Tank-shell load sequence — pop top → seat tube → unscrew bottom in bore → close breech → rocket ready (continuity).
Does not prove: Ballistic accuracy, fuze, motor impulse.
| Item | Detail |
|---|---|
| Entry | 1A passed; alloy tube mock with foil contacts; inert round mock optional |
| Procedure | Trained operator completes load under 10 s target; measure continuity resistance/LED; repeat 20 cycles |
| Pass | Continuity detected within 200 ms of breech lock; no bind on tube insert; bottom cap removable in bore with gloved hands |
| Tolerances | Rim concentricity and seat preload per Annex F tolerance table |
| Fail | Intermittent continuity; tube bind; cap cross-thread |
| Artifacts | Load-time log, continuity trace, CONTAINER-SPEC checklist signed |
| Annex | CONTAINER-SPEC · F gunner sequence |
Proves: Front trigger → seeker power + steady lock tone simulation; rear fire blocked until tone; rear requires front held; abort on front release.
Does not prove: Field lethality, real IR lock on drones.
| Item | Detail |
|---|---|
| Entry | 1A + 1B passed; fire-control breadboard or launcher wiring harness |
| Procedure | Matrix test all trigger combinations; verify retention interlock follows tone sim |
| Pass | Rear inert fire output only when front held and tone active; releasing front aborts within 100 ms; no rear-only path |
| Fail | Rear fires without tone; retention releases early |
| Artifacts | Interlock truth table signed, wiring diagram as-built |
| Annex | F § Controls · DOC-06 interlock diagram |
Requires a partner or range — see DOC-11 — Live-fire and partner validation and data/live_fire_results.template.json.
| Gate | ID | Proves | Depends on |
|---|---|---|---|
| Motor static fire | 2A | Impulse, (F(t)), backblast vs 10 yd | DOC-09 motor vendor brief |
| Instrumented launch | 2B | v @ 1000 m in 330–350 m/s; TOF | 2A + range access |
| Warhead arena | 2C | Cone ~10–12 ft @ ~20 ft | Fuze + arena |
| Seeker HIL | 2D | Lock tone vs threat class | Seeker hardware |
Phase 2 exit: Populate live_fire_results.json with measured data; set Annex I live-fire row to Partner validated when gates 2A–2B (minimum) pass.
Traceability matrix: Annex I — Validated vs notional.
Phase 1 is complete when 1A, 1B, and 1C pass on the same launcher generation with documented artifacts. Only then authorize Phase 2 funding for motor/grain static test.
