Technical details +
914 × 124 mm body; 18–24 nmi mission endurance.
Passive acoustics: 1–3 kHz with variable power. Echo mode: 3–13.5 kHz, ranging error under 150 yd.
Programmable speed, depth, heading and acoustic profile.
Mk1 ship-launched; Mk2 air-launched with MAD up to 25 m.
Operates up to Sea State 4; sinks automatically after the mission.
Detects ultra-low-frequency underwater sources and determines their bearing from a single unit. Networked nodes triangulate the source for passive surveillance, localisation and tracking.

250–2000 Hz
Bearing accuracy
±5°
Tested depth
300 m
Direction of arrival
1 unit
Technical details +
Bearing detection from a single unit, with no hydrophone array.
LOFAR ultra-low-frequency detection and multiple-target tracking.
Waterfall and bearing-plot displays with AI/ML anomaly detection.
A celestial navigation aid for ships that fixes position and true-north heading from the stars by night and the Sun by day, with no GNSS to jam or spoof.
A ship-borne unmanned helicopter for maritime domain awareness and C4ISR. Designed to launch and recover from a ship’s flight deck in varying sea states.

Technical details +
Load capacity: 25 tons.
Weight: 205 kg per 25 m roll.
Structure: honeycomb panels made from lightweight, high-strength polymers.
Roll dimensions (L × W): 25,000 × 1,000 mm. The system comprises two 1 m-wide Class 24 tracks.
Tested on 4×2, 4×4, 6×6 and 8×8 vehicles.
Tested to Military Load Classification (MLC) 24 baseline, with capability for vehicle loads up to MLC 30+ in desert and semi-desert conditions.
Operating temperature: −50 °C to +60 °C.
Service life: minimum 10,000 passes / 8 years.
Transport: approximately 10+ rolls in one level in a standard 4×4 truck with a 2.0 m × 4.5 m cargo bay.
Interconnected rolls create a virtually indefinite road length. Modular construction accommodates bends and turns; deployment requires no special troop training.
Applications: assault trackways, temporary roadways, approach roads, gap crossings, beach landings and flooring systems. Additional accessories enable use as a helicopter landing mat.
Fully localised — 100% Made in India. Intellectual property: Altair Infrasec Private Limited.
A hybrid inflatable decoy that mimics the visual and infrared signatures of the Su-30 MKI. A steel structure and PVC tensile fabric combine in a blower-supplied system assembled by a four-person crew.
