MCM100

The Avon Protection MCM100 is a state-of-the-art, electronically controlled closed-circuit mixed gas military rebreather (eCCR). Developed in collaboration with the UK's Defence Science & Technology Laboratory (Dstl) and the Royal Norwegian Navy, the MCM100 is engineered for Explosive Ordnance Disposal (EOD), Mine Countermeasures (MCM), and Special Operations diving. Featuring ultra-low magnetic and acoustic signatures compliant with STANAG 2897 Class A standards, the system eliminates bubble emissions and minimizes sea mine detonation risks. Capable of diving down to 100 meters (328 feet), the MCM100 incorporates dual-redundant electronics, a mouthpiece Head-Up Display (HUD), and wrist-mounted dive display, automatically controlling partial oxygen pressure ($PPO_2$) to maximize operational safety, gas efficiency, and stealth for tactical underwater operators.

  • STANAG 2897 Class A Low Magnetic & Acoustic Signature: Engineered specifically for MCM and underwater EOD missions to prevent triggering magnetic or acoustic naval mines.
  • Electronically Controlled eCCR with Dual Redundancy: Features multiple oxygen sensors and dual independent microprocessors to automatically maintain setpoint $PPO_2$ for ultimate life support safety.
  • 100m Depth Capability & Intuitive Mouthpiece HUD: Supports Air, Nitrox, and Trimix/Heliox gases, equipped with an integrated mouthpiece LED HUD for hands-free visual system status.

Scope of Application

  • Underwater Explosive Ordnance Disposal (EOD): Naval EOD units conducting clearance and neutralizations of sea mines, unexploded ordnance, and underwater IEDs.
  • Mine Countermeasures (MCM): Channel clearing, minefield reconnaissance, and stealth mine sweeping in high-risk naval zones.
  • Special Forces Covert Sub-Surface Infiltration: Combat divers and naval special warfare units executing bubble-free, silent sub-surface infiltration.
  • Deep Sea Salvage & Military Underwater Engineering: Deep-water rescue down to 100m, wreckage inspection, and tactical sub-surface equipment recovery.

The Tactical Pinnacle in Subsea EOD & Stealth Warfare: Avon MCM100 Military Rebreather

  • High-Risk Subsea EOD Clearance: Ultra-low magnetic and acoustic signatures prevent triggering sensitive naval mines, allowing technicians to work safely.
  • Covert Sub-Surface Operations: Fully closed-circuit design blocks bubble formation at the surface, ensuring total stealth during covert infiltration missions.
  • Deep Water Decompression Optimization: Automated $PPO_2$ control optimizes gas mixtures to reduce decompression times during deep 100m operations.

Value&Benefits

The Avon MCM100 resolves the severe limitations of open-circuit systems and high-magnetic rebreathers that expose diver positions or trigger naval mines. Combining defense-grade engineering from the UK and Norway, Avon Protection delivers unmatched safety redundancy and subsea stealth. Backed by factory support and training, it maximizes mission success and diver survivability for naval defense forces.

  • Maximizes Subsea EOD Safety: Fully compliant Class A low-magnetic signature protects technicians from acoustic and magnetic mine hazards.
  • Extends Sub-Surface Dive Duration: Closed-circuit gas recycling maximizes gas efficiency, supporting multi-hour mission profiles.
  • Reduces Operator Cognitive Load: Intelligent HUD and wrist displays provide real-time visual alerts, allowing divers to remain focused on the mission.

Performance

  • Rated for deep tactical diving missions down to 100 meters (328 feet).
  • Fully certified to STANAG 2897 Class A magnetic signature requirements.
  • Integrated high-efficiency CO2 scrubber canister provides extended gas purification.
