JFD Global (James Fisher and Sons subsidiary) developed Stealth Multi-Role was created to solve a key problem for modern military divers: the need to use different systems for different missions. It has combined deep mine clearance (MCM/EOD) and shallower, but sustained, special operations (SOF) functionality into a single platform.
Main technical features:
- Impressive depth of action: SMR is capable of operating safely up to For a depth of 120 meters, using mixed gases (Heliox/Trimix). This makes it one of the deepest series-produced defense sector rebreathers in the world.
- Extreme Endurance: The system is capable of providing life support up to 12 hoursThis is vital in missions where the diver must cover long distances underwater.
- Modular and software-driven architecture: Unlike older generation fully mechanical devices, the SMR uses modern electronics and sensor logic, maintaining a constant partial pressure of oxygen ($PO_2$). The software base allows the device to be regularly updated and integrated with underwater vehicles or tactical navigation.
- Stealth: As the name suggests, the device has extremely low acoustic and magnetic radiation (corresponds to NATO STANAG Class A), which prevents the detonation of sea mines.
Comparison with other popular CCR systems
To understand JFD SMR's place in the market, it is best to compare it with its closest competitor from Avon Protection, as well as with military classics from Dräger.
Avon Protection MCM100
Avon MCM100 is currently one of the most popular and innovative multi-role military respirators, which has also recently received significant digital updates.
- Similarities: Both devices target the same audience (SOF and deep-sea MCM divers), support mixed gases, are electronically controlled (eCCR), and both have excellent protection against magnetic and acoustic detection.
- Differences: MCM100 The standard training and CE certified depth is around 100 meters, while the JFD SMR is positioned with an even greater (120 m) margin. Avon The system stands out with its 100% digital ecosystem – it has gotten rid of analog sensors, implemented Bluetooth data transmission, as well as surface managers can monitor the diver in real time in a 3D environment and keep track of their sensors. The JFD SMR, on the other hand, stands out with its 12-hour operating time (the MCM100's operating time exceeds 4 hours at high load, but does not reach the JFD's figures in extreme settings).
Dräger LAR series (e.g. LAR 8000)
German manufacturer Dräger The LAR series has been the “workhorse” of tactical divers (such as the US Navy SEALs) for decades.
- Similarities: Extreme reliability and complete absence of bubbles, ensuring maximum concealment in shallow waters.
- Differences: Dräger devices have traditionally been focused on the use of pure oxygen ($O_2$). LAR 8000 can operate in both closed-cycle $O_2$ mode (very shallow, up to ~7-10 m due to high oxygen toxicity), and in semi-closed (SCR) mixed gas mode (up to ~40 m). JFD SMR against this background is a completely different generation and scale of equipment, capable of providing a depth of 120 meters and a complete closed cycle (CCR) without gas losses, making JFD much more suitable for serious deep-sea mine clearance.
Technical summary table
| Parameter | JFD Stealth Multi-Role (SMR) | Avon Protection MCM100 | Dräger LAR 8000 |
| Operating environment | Multifunctional (MCM/SOF) | Multifunctional (MCM/SOF) | Tactical (Shallow SOF) |
| Maximum depth | Up to 120 m | Up to 100 m | ~10 m ($O_2$) / ~40 m (Nitrox) |
| Duration of operation | Up to 12 hours | >4 hours (at high load) | Up to 4 hours (in $O_2$ mode) |
| Control system | Electronic (eCCR), software-driven | Electronic (eCCR), fully digital | Mechanical / pneumatic |
| Radiation signature | Ultra low (STANAG) | Ultra low (STANAG) | Ultra low (STANAG) |
In summary, the JFD SMR is a massive leap forward in both mission planning and diver safety. It combines depth and incredible battery/scrubber endurance, making it one of the most capable systems for heavy underwater tactical missions, rivaled only by modern equipment such as the Avon MCM100.
