The advanced waterjet AWJ-21 is an underwater discharge
waterjet designed to reduce ship signatures and at the
same time deliver high efficiencies. Its layout also
enables the designer to eliminate rudder and waterbourne
shafting. Units are protected from grounding by the
pump nacelle.

Features and benefits
- Greatly improved cavitation characteristics
- High efficiency over broad operating range
- Shock hardened component design
- Single hull penetration for steering and reversing
system
- Drive-train flexibility
Testing in the US Navy’s 40metre AESD will optimise
and validate AWJ-21 pump performance and to determine
power, manoeuvring, hydrodynamic and hydro-acoustic
performance. It is expected to provide a stealthy, more
compact propulsion system with reduced weight and volume.
Ideal for operating in shallow waters.
