REGENT Completes Maiden Flight of “Squire” Autonomous Seaglider Drone

On April 13, 2026, Rhode Island-based aerospace company REGENT (Regional Electric Ground Effect Nautical Transport) successfully conducted the maiden flight of its “Squire” autonomous seaglider drone. Taking place in Narragansett Bay, the event marks the first flight of a defense-specific wing-in-ground-effect (WIG) craft in the United States. According to the company’s press release, the Squire is designed to provide high-speed, runway-independent logistics and reconnaissance capabilities for the U.S. military.

The successful demonstration was officially cleared by the United States Coast Guard, which serves as the primary regulator for seaglider vessels. By bridging the gap between maritime vessels and aviation, REGENT aims to sustain dispersed military forces in contested maritime environments, particularly supporting the U.S. Marine Corps in the Indo-Pacific region.

During the test, the drone reached speeds of 40 knots as it became airborne. The company noted that the Squire’s development runs parallel to the sea trials of REGENT’s “Viceroy” prototype, a larger, 12-passenger commercial seaglider. This parallel testing allows the manufacturer to share data and accelerate both its commercial and defense programs.

The Mechanics of the Squire Seaglider

Wing-in-Ground (WIG) Technology

According to REGENT, the Squire operates using the wing-in-ground (WIG) effect. A WIG craft flies just a few feet above the water’s surface, at an altitude roughly equal to or less than half its wingspan. This aerodynamic profile traps compressed air between the wings and the water, creating a “cushion” that significantly reduces drag and increases lift. This allows the vehicle to travel faster and carry heavier payloads more efficiently than conventional boats or aircraft. REGENT classifies the Squire as a “USA-V” (Unmanned Surface and Aerial Vehicle), combining the persistent presence of an unmanned surface vessel with the speed of an unmanned aerial vehicle.

Flight Profile and Specifications

The recent demonstration showcased the Squire’s autonomous ability to transition through three distinct modes of travel. In “Hull Mode,” the craft floats and maneuvers on its boat-like hull. It then accelerates into “Foil Mode,” utilizing retractable hydrofoils to lift the hull out of the water and drastically reduce hydrodynamic drag. Finally, it enters “Flight Mode” by retracting the foils and taking off into wing-in-ground-effect flight.

While the test flight hit 40 knots, REGENT states that the fully operational Squire is being built to reach a top speed of up to 70 knots (approximately 81 mph) with an operational range of over 100 nautical miles. The drone features a payload capacity of 50 pounds, housed in a payload bay measuring 14 inches long, 12 inches high, and 14 inches wide, providing 2,400 cubic inches of internal volume. The company highlights that this internally mounted bay is designed for rapid reconfiguration by a two-person crew requiring minimal specialized training.

Strategic Military Applications

Solving Contested Logistics

The U.S. Marine Corps and the broader joint force are actively seeking solutions to sustain small, distributed units across vast maritime spaces. According to the provided research, the Squire addresses a critical vulnerability in “contested logistics” because it does not rely on traditional infrastructure like deep-water ports, roads, or airfields, which are highly susceptible to enemy strikes. REGENT is explicitly positioning the platform as a strategic asset to counter anti-access/area denial (A2/AD) capabilities in the Indo-Pacific region.

The drone is optimized for a variety of mission sets, including Intelligence, Surveillance, and Reconnaissance (ISR), tailored logistics and resupply, combat search and rescue (CSAR), counter-narcotics, and anti-submarine warfare (ASW) support. Furthermore, its low-altitude flight profile gives it a low radar signature, keeping it below conventional line-of-sight radar systems.

To date, REGENT has been awarded $15 million in contracts by the U.S. Marine Corps. Earlier in 2026, REGENT leadership presented the Squire program to Defense Secretary Pete Hegseth and senior military staff, emphasizing its potential to rapidly close time-critical logistical gaps in the field.

Leadership Perspectives

Company executives emphasized the strategic importance of the successful test flight in their official statements.

“This successful flight milestone is a major success for our defense program and a strong signal of what Seaglider technology can deliver for the warfighter. There are no products in the market today that combine the speed and wave tolerance of Squire at such a compelling price point. This will revolutionize maritime warfare.”

“Defense customers require platforms that can operate across wide maritime areas with speed, range, and mission flexibility, without relying on traditional and often vulnerable infrastructure. Squire is designed to meet that exact need.”

AirPro News analysis

We view the successful flight of the Squire as a fascinating intersection of historical physics and modern autonomous technology. The wing-in-ground effect is not a new concept, it was most famously utilized during the Cold War by the Soviet Union’s massive “Caspian Sea Monster” ekranoplans. However, applying this aerodynamic principle to a compact, autonomous, all-electric drone solves a very modern U.S. military aircraft problem. As the Pentagon shifts its focus toward distributed maritime operations in the Indo-Pacific, the ability to supply troops on remote islands without relying on easily targetable runways is paramount. The “runway-free” nature of the Squire, combined with its low radar signature, positions it as a highly relevant tool for modern naval and amphibious warfare.

Frequently Asked Questions

What is a seaglider?

A seaglider is a type of wing-in-ground-effect (WIG) craft that operates a few feet above the water’s surface. It combines the operational characteristics of a boat with the speed and aerodynamics of an aircraft, utilizing a cushion of trapped air to reduce drag and increase efficiency.

How fast can the REGENT Squire fly?

During its maiden test flight, the Squire reached speeds of 40 knots. However, the fully operational production model is designed to achieve a top speed of up to 70 knots (approximately 81 mph).

Who regulates the testing and operation of seagliders?

In the United States, seagliders are primarily regulated as maritime vessels. The recent testing of the Squire in Narragansett Bay was officially cleared by the United States Coast Guard.
