While the government did not publicize the delivery schedule for the drones, the rollout will occur in phases to ensure operational continuity and crew training.

Expanding Airborne Assets
The Hermes upgrade is part of the Singapore Armed Forces’ plan to boost automation, resilience, and situational awareness through advanced technologies by 2040.

It is also the Singaporean Air Force’s second major airborne platform acquisition in two months, following September’s announcement that it would buy four Boeing P-8A Poseidon maritime patrol aircraft, expected to enter service in the early 2030s.

The same month, Hermes 900 developer Elbit Systems reported a $120-million contract to supply drones to an undisclosed international customer for long-range coastal surveillance, now believed to be Singapore.

Israel’s Hermes 900
Designated the Kochav in the Israel Defense Forces, the Hermes 900 UAS is controlled by a two-man ground crew.

It has a length of 8 meters (26 feet), wingspan of 15 meters (49 feet), payload capacity of 350 kilograms (772 pounds), and a maximum takeoff weight of 1,180 kilograms (2,601 pounds).

The drone is powered by a 210-horsepower Rotax 916 engine for a service ceiling of 9,100 meters (29,856 feet), speeds up to 120 knots (37 kilometers/23 miles per hour), and a range of 9,000 kilometers (5,592 miles).

It has a flight time of 36 hours and can be equipped with armaments, including Spike fire-and-forget anti-tank/anti-personnel guided missiles, also manufactured by Israel.

The value of the contract awarded to IAI for this Military Base Defence Development Project was worth THB3.44 billion (US$108 million). The RTAF Logistics Department said the first phase of the project would see the procurement of one Barak MX launcher battery.

The battery will be operated by the Antiaircraft Regiment of the Security Force Command. The Barak MX is able to intercept aircraft, drones, cruise missiles and even ballistic missiles when using the extended-range effector.

Regarding this procurement, the RTAF stated, “The air force must be prepared for future threats by procuring modern weapon systems to enhance air defence, which currently faces limitations in dealing with emerging threats effectively.”

This integrated air defence system was mentioned in an RTAF White Paper published on 29 February 2024. That document prioritised a medium-range air defence system possessing a minimum 56km range from FY2025-28. It was to be followed by phase two from 2033 for more medium or even long-range missiles.

The fact that a contract has been so quickly signed likely stems from Thailand’s brief border war with Cambodia in July this year.

At that time, Cambodia deployed various surface-to-surface weapons that could strike over the border into Thai territory. Examples included Soviet-era BM-21, Czech-built RM-70 and Chinese Type 90B rocket launchers. Cambodia’s longest-range system is PHL-03s that have a range approaching 150km, with these arriving from China in mid-2022.

The RTAF deployed various aircraft in the brief border clash with Cambodia, and it made use of the Wing 21 air base in Ubon Ratchathani, and the Wing 1 base in Korat.

IAI introduced the modular Barak MX system back in 2018. It can incorporate four types of missile: the 15km-range Barak SR, the 35km-range Barak MR, the 70km-range Barak LR and the 150km-range Barak ER.

Israel used the Barak MX operationally from land and sea platforms to defend against Iranian missiles during Operation Rising Lion in June this year.

The aforementioned RTAF White Paper also listed other air defence requirements for the RTAF. From FY2028-2032, a short-range air defence system boasting cannon, missile and laser effectors is required. Credence is given to counter-drone systems too, and a nine-year project to procure these commenced in 2025. The RTAF also requires a wider command-and-control capability that includes an integrated ground operations centre.

Thailand is a keen buyer of equipment from both China and Israel. The Thai military previously acquired KS-1C and FK-3 air defence systems from China, so it is unclear why it has now turned to IAI.

Current areas of Israeli-Thai cooperation include the D11A multiple rocket launcher (a localised version of Elbit Systems’ PULS), the M758 Autonomous Truck-Mounted Gun (based on the ATMOS), and the M361 Autonomous Truck-Mounted Mortar that features the Elbit Systems Spear 120mm mortar.

The Barak MX could potentially arm warships of the Royal Thai Navy in future too, especially with a new frigate procurement programme now on the cards.
