The Royal Navy has successfully tested its ability to counter airborne drone threats.

In a first-of-its-kind air-to-air trial, a Wildcat helicopter equipped with the Martlet missile engaged and destroyed a fast-moving Banshee drone over the Bristol Channel.

This trial, held off the Welsh coast at the Manorbier range, demonstrated the Wildcat’s autonomous capability to detect, track, and neutralise aerial threats without external assistance.

The trial highlights the versatility of the Martlet missile, initially designed to counter small, manoeuvrable surface targets like speedboats.

The Royal Navy’s decision to test it in an air-to-air role underscores the missile’s adaptability in addressing a range of threats. Commander James Woods, Commanding Officer of 815 Naval Air Squadron, praised the development, stating, “This is a significant advancement in maritime strike capability for the Royal Navy that further refines our ability to deter and neutralise airborne threats.”

The two-day exercise involved launching the Banshee drone to simulate a realistic, high-speed aerial target, pushing the Wildcat’s response time and accuracy. As the Wildcat helicopter locked onto its target, it received the command to proceed with the missile engagement, which culminated in a successful intercept.

Lieutenant Dave Guest, the Wildcat pilot, highlighted the importance of this new capability: “It’s crucial that we demonstrate the Wildcat’s effectiveness in engaging targets like uncrewed systems – and that we can do so independently, without assistance from other assets.” He noted the importance of the Martlet as a “highly-capable and cost-effective weapon in our arsenal.”

The addition of Martlet’s air-to-air capability complements the Wildcat’s existing arsenal, which includes the Sea Venom missile. Together, these missile systems enhance the helicopter’s operational flexibility, allowing it to tackle a wide range of targets, from enemy vessels to drones. This versatility is particularly valuable in high-threat regions like the Red Sea, where Royal Navy assets have increasingly encountered drone threats. Earlier this year, a Wildcat deployed on HMS Diamond faced multiple drone threats from Houthi rebels in the Gulf of Yemen, underscoring the pressing need for robust anti-drone capabilities.

Martlet, a lightweight, laser-guided missile, was originally acquired to engage small, fast-moving surface vessels. Since its introduction during the UK Carrier Strike Group’s deployment in 2021, the missile has undergone rigorous testing in various operational scenarios, affirming its utility against both surface and aerial threats. The Royal Navy’s investment in this capability aligns with its broader strategy to enhance maritime security against rapidly evolving threats.

In the air-to-air role, the Wildcat’s agility allows it to respond swiftly to incoming drones, providing a mobile counter-drone screen that can be repositioned as needed, all while retaining its anti-surface capabilities.

  1. Hmm, that is pretty impressive given the Banshee is a fast drone, reportedly 720km/h. Obviously the engagement envelope for any helicopter is going to be pretty narrow as the helicopter’s ability in ‘intercept’ such a fast drone will be limited. The test could have been with the Banshee flying at a lower speed, of course. Nevertheless a very useful extra capability for the RN, especially as the Wildcats often fly from T45 destroyers with very capable radars.

    I looked up the Banshee after reading the above article and it appears that the Banshee has been supplied to Ukraine as a one way suicide drone with a 7kg warhead and wreckage has been found int Russia. The version apparently used has a one way range of 200km…

    Cheers CR

    • They used the propeller powered Banshee for this one, so a roughly equivalent target to a Shared but slightly faster and stealthier.
      I suppose the best way to use this for air defence would be to have the helicopter in the air and up the threat axis when the first warning of a launch is given, and then use the ship to vector on to targets as they approach.
      There might be issues with friendly fire if the ship then fires its own missiles but I can’t think of another way of having the Wildcat in the air and within the 7km range with enough time to spare.

  2. Shoot it or drown it?

    This is a useful capability when needed.

    Cheap low tech mass produced drones are my concern, let’s not spaff away our limited expensive weapons on cheap disposable drones. Exhaust a ship of its weapons and its effectively a mission kill. We need a counter that does not cost many many thousands per shot and can be replenished at sea.

  3. How does this work? A ship detects a fast incoming drone, at what range can a drone be detected? It launches a helicopter to take out the drone! By thr time it’s airborne it’ll be too late. Why does it need a helicopter to down a drone, shouldn’t the ship have this capability?

    • The ships do have this capacity but if you’ve got a helicopter already up and armed, it’s better to utilise the heli to defend targets like tankers with the Martlet if possible. The Martlet costs £20,000 whereas the Aster 15 costs roughly £1m and the Sea Ceptor costs around the £2m mark.

      If you’re in a hostile area where a drone attack is likely, utilising a Wildcat is far more cost effective.

  4. Very expensive way of taking down cheap drones. There has to be a better way via laser or other sorts of discombobulation of incoming threats.

    • Martlet is very cheap, around £20,000 per missile. A WildCat can carry up to 20 rounds and rapidly be vectored by a destroyer or carrier (with the longer ranged radars) to expected axis of attack and be in a position to intercept multiple drones away from a ship to task group. Many of the ‘cheap’ Iranian drones are not as cheap as people make them out to be nor are they really drones, a data leak from the Russian sided revealed that they were paying around $150,000 per Iranian built Shahed 136 and even more for some of the other variants. These ‘drones’ have more in common with something like a V-1 than a quadcopter DJI.

      You can’t rely on EW for all of them either, many of them follow a preprogrammed flight path and are not controllable once launched. There are no radio signals that can be interrupted and the idea of ‘hacking into them’ as many people say is pure fantasy. Lasers work but at very short ranges, you wouldn’t want be carrying out multiple engagements in a >1km envelope from your ship, using a helicopter with a large magazine of these cheap munitions offers the best redundancy, engagement range and flexibility to adapt to different threats over that of any low cost ship bourne weapon system.

  5. Nothing a prop driven plane with six 50 caliber machine guns couldn’t do cheaper, think along the lines of a p51mustang with a turboprop, 500 mph in level flight and built for the price of a helicopter.

  6. I’m ex Royal Artillery, Air Defence…we used the Javelin MANPADS. My time was late 90s to early 2000s. We would shoot Banshees over the sea from Manorbier. The banshee is a slow, low, rather large drone. It was effortlessly hit.

    That 25 years later, a modern naval helicopter…can shoot one down….

    That’s not news. That’s like saying…”we tested the Cromwell tank today in 1947 and in a exercise costing millions, we showed it could defeat an A7V.

    You have to puzzle at this. Who is it impressing? There’s a certain part of me that thinks it’s going to the public. That we have capacity to defeat drones. Make everyone think we are effective and safe.

    Twas always thus.

  7. Why are you even worried about drones when there are hundreds of people coming through the channel illegally every day surely they should be stopped as a priority…..! C#nts 🤬🤬🤬
