Squad / SOF Mid-Range Drone Destroyer — 60 mm Class
RADR is a lightweight, reusable 60 mm shoulder-fired recoilless rocket system for squad and SOF — a mid-range drone destroyer that emphasizes speed-to-target, simplicity (KISS), reliability, and one-person reload. It engages Group 1–2 threats (FPV, quadcopters, loitering munitions, terrain-matching/gliding drones) as a mid-range counter-UAS weapon when machine guns fall short and SAM is too heavy to allocate.
Status: Phase 0 — Conceptual
Version: 1.8.2
| Stowed — bar flush on forward sleeve | Deployed — shoulder bar at 12→6 (vertical) |
|---|---|
 |
 |
Thin ~6 in fold-down bar on the forward black sleeve; visible hinge; no fixed shoulder stock. Full geometry: shoulder bar spec.
Tank-shell tube (stays in launcher; rocket flies free) · Pop top → load → unscrew bottom in bore → close → rocket ready. Art: side left = top, right = breech. Spec: CONTAINER-SPEC.
18 in self-contained round inside the tube; fins stowed for clearance. Left = nose (seeker), right = tail (nozzle). Spec: ROUND-SPEC.
The gunner rough-aims on a fold-out display fed by an integrated digital camera-style sight (smooth 1×–20× zoom via foregrip + / −). RPG-style shouldering — arm’s-length view on the panel; no cheek weld or perfect sight picture required. Holding the front trigger powers the round’s 100 mm IR fire-and-forget seeker and yields a steady lock tone; the rocket retention stop disengages only then. Pulling the rear trigger (while holding front) launches the 18-inch round from an alloy protective tube. A mildly progressive solid motor drives closure to ~330–350 m/s at 1000 m. Moderate-maneuver nose canards trim the flight path; four swept spring-loaded fins deploy at exit and mechanically lock open. At ~20 ft, radar or millimeter-wave proximity (with timed backup) fires a pyrotechnic dispersal charge that throws 300 × 7 mm rough-edged dense alloy cubes in a forward-biased cone (~10–12 ft wide). The cubes kill — not a kinetic rod.
Philosophy: Speed is the primary defense · KISS + rugged · One-person reload · Honest capability ceiling.
Launcher: Modernized M1 Bazooka — 40 in tube (≤ 5.5 kg empty), matte camo, Gustav-style flip breech (spring bolt + positive deadbolt lock), dual pistol-style triggers (rear grip just aft of sight module; front slightly smaller; + / − zoom on foregrip aft face, wired to sight + display), 6 in fold-down shoulder bar (slim rounded pad, stows flush on barrel; deploys 12→6 vertical — no add-on end cap), no fixed shoulder stock, slightly rear-biased balance.
| Threat class | Examples / notes |
|---|---|
| FPV kamikaze drones | Close-in attack profiles; high closure rate |
| Small-to-medium quadcopters | ISR, spotter, and light attack platforms |
| Loitering munitions | Orbiting or diving engagement profiles |
| Terrain-matching / GPS-denied gliders | Low-signature glide profiles (e.g. Hornet / “Martian” class) |
| Group 1–2 UAS (general) | Swarm and interdiction attacks in the close fight |
RADR is not sized for large Group 3+ platforms or long-range aircraft.

Full matrix: Annex I — Validated vs notional traceability.
| Layer | Function |
|---|---|
| Rocket retention stop | Mechanical stop in barrel prevents round sliding forward when slung or carried; disengages only when breech is fully closed, gunner holds front trigger, and seeker outputs steady lock tone; re-engages if front is released |
| Breech deadbolt | Positive mechanical lock when closed — no seeker or retention release until tube seated |
| Dual-trigger interlock | Rear fire blocked until lock tone; front must stay held through ignition |
| No override | No rear fire without tone; no seeker until tube seated |
| Backblast discipline | ≤ 10 yd (30 ft) cleared to rear before every shot and before breech re-open |
- Open breech — pull spring-loaded bolt handle and swing breech open
- Pop top (PULL tab) on alloy tube
- Slide tube into launcher bore until seated
- Unscrew bottom screw cap in bore (gloves OK)
- Close breech — deadbolt snap → rocket ready (electrical continuity)
- Hold front trigger — seeker + lock tone; retention stop disengages
- Pull rear trigger (front held) → rocket flies free (recoilless vent ≤ 10 yd rear)
- Open breech — spent protective tube drops out for reload
Carry: Launcher + one round ≤ 9.0 kg — one person can reload. Retention stop engaged whenever front trigger is not held.
