Greece expands V-BAT maritime drone fleet

Greece is expanding its fleet of Shield AI V-BAT unmanned aircraft, adding vertical-take-off surveillance capacity for maritime domain awareness across the Aegean Sea.

The Hellenic Army already operates V-BAT for intelligence, surveillance, and reconnaissance missions. Additional systems will strengthen coverage in an operating environment defined by islands, confined launch sites, busy sea lanes, and contested maritime approaches. Runway-independent aircraft give users more options to deploy sensors from ships, small bases, and austere locations without relying on larger airfields.

V-BAT is a NATO Class I vertical-take-off-and-landing system built around a ducted-fan design. It uses a heavy-fuel engine, offers endurance of more than 12 hours, and can operate from ship decks, rooftops, and confined terrain. Those characteristics fit the Aegean, where surveillance assets need to be dispersed and persistent rather than concentrated around a few large bases.

Maritime surveillance places specific stress on unmanned aircraft. Saltwater corrosion, deck movement, wind turbulence, vibration, limited maintenance space, and long hours over water all affect reliability. Sensors must identify vessels, track movement, and support decision-making in crowded maritime areas where civilian and military activity overlap. The aircraft also has to feed data into command networks quickly enough to give operators useful options.

Shield AI’s plan to expand its presence in Greece adds an industrial support layer. Unmanned fleets become difficult to sustain without regional training, spares, maintenance, software support, and customer feedback loops. An Athens presence can support operators more closely, help tailor the system to local missions, and provide a base for future partnerships with Greek industry.

The aircraft’s autonomy software is part of the attraction. V-BAT is designed to operate in environments where GPS and communications may be degraded, a problem already pressing on military and civil infrastructure. The wider vulnerability of positioning, navigation, and timing systems, explored in the invisible war on GPS, is especially acute for unmanned systems operating near contested maritime boundaries.

Production and sustainment pressures differ from larger aircraft programmes, but they are no less important. Small unmanned systems need airframes, engines, payloads, antennas, ground-control stations, ruggedised transport equipment, and software updates. Fleet scale can become a maintenance burden if spare parts, trained technicians, and repair processes do not grow with aircraft numbers.

The maritime role also demands payload flexibility. Electro-optical sensors, communications relays, electronic-support payloads, and other mission equipment can all be relevant, but every payload change affects endurance, balance, power use, and operator workflow. Manufacturers therefore have to balance modularity with reliability, especially for customers that need rapid adaptation but cannot accept fragile field performance.

V-BAT’s shipboard operation places it within a broader naval shift towards uncrewed systems. The production move behind the Boeing MQ-25A sits at a much larger scale, yet the direction is similar: maritime forces want unmanned aircraft that can operate routinely from naval environments, reduce risk to crewed platforms, and extend sensing range.

For Greece, distributed surveillance is particularly valuable. Island geography favours systems that can be launched from small sites and repositioned quickly. A vertical-take-off UAV can support maritime security, border surveillance, search and rescue support, and military ISR without the infrastructure demands of conventional runway-dependent aircraft.

Greece’s expanded V-BAT fleet shows how maritime ISR is becoming more distributed, autonomous, and production-sensitive. The aircraft gives operators additional reach across a complex theatre, while the supporting industrial model will determine whether that reach can be maintained over years of operational use.
