4 top-level parts · 4 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Descent Parachute | 1× | Small ribbon canopy limiting descent to roughly 25-40 m/s and keeping the buoy nose-down for clean water entry. |
| 2 | Parachute Riser | 1× | Webbing link between canopy and buoy body, cut or released at splash. |
| 3 | Water-Entry Release | 1× | Impact- or water-sensing release that discards the parachute so it cannot foul the antenna or float. |
| 4 | Rotochute Vanes | 1× | Low-altitude variant |
