Engineered for the11,000-metre breach.
Autonomous titanium-ceramic submersibles engineered to endure 1,100 bar hydrostatic pressure in the Mariana, Puerto Rico, and Kermadec trenches without umbilical tether.
Vertical Sounding: Epipelagic Zone
Sunlight & Surface Calibration
Surface layer with primary GPS telemetry acquisition, hull sensor calibration, and negative buoyancy trim confirmation.
Vehicle Architecture & Pressure Hull
Engineered from Grade 5 titanium, borosilicate syntactic foam, and magnetic-induction propulsion to withstand 1,114 bar crushing pressure without mechanical failure.
Grade 5 Titanium Dual-Hemisphere Shell
Precision-machined from two solid forged titanium billets in Brest, diffusion-bonded along the equatorial seam. Houses all core flight compute, inertial guidance, and scientific telemetry payloads in an unpressurized 1-atmosphere internal environment.
Hadal Bathymetric Sensor Suite
Equipped with multi-sensor payloads calibrated for extreme hydrostatic pressures, delivering sub-decimeter topographical mapping and in-situ chemical spectroscopy.
Synthetic Aperture Sonar
Wide-swath bathymetric interferometer generating real-time centimeter-accurate 3D point clouds of the hadal seafloor, sub-bottom strata, and trench scarp formations.
Ultra-Deep CTD Probe
Calibrated oceanographic sensor measuring Conductivity, Temperature, and Depth. Captures in-situ salinity gradients and physical sound velocity profiles down to 10,928 metres.
Laser Raman Spectrometer
Deep-sea optical spectrometer focusing a green laser beam through a sapphire window to identify mineral crystal lattices, dissolved gas phases, and hadal hydrothermal chemistry.
Isobaric Benthic Sampler
Articulated hydraulic rotary corer engineered to recover trench-floor sediment and benthic microorganisms while retaining ambient hydrostatic pressure during ascent to surface.
Hadal Trench Mission Dossiers
Verified field records of uncrewed autonomous dives executed in the deepest hadopelagic trenches on Earth.
