Development

The Milkor 380 was developed from the earlier MA80, which was an 80 kg demonstrator that undertook its inaugural flight in 2017. The Milkor 380 has since evolved into a more sophisticated platform featuring an enhanced systems architecture, with its first flight occurring on September 19, 2023.

Following this, the prototypes have completed numerous test flights under the oversight of the South African Air Force (SAAF), which is conducting the operational testing and evaluation of two airframes at an airbase in the Western Cape. The unmanned aerial vehicle (UAV) has undergone extensive performance assessments, highlighting its capabilities across a broad spectrum of operational parameters.

Milkor (Pty) Ltd of South Africa conducted the maiden flight of Model 380 UAV at Air Force Base Overberg, located near Bredasdorp, on September 19, although immediate confirmation of the flight was not obtained. Flight trials are anticipated to continue throughout the remainder of 2023 and into the first quarter of 2024 at Overberg, which serves as the operational base for No. 525 Squadron and the SAAF’s test flight and development centre.

Reports indicate that five additional aircraft are currently in production, with expected delivery in the following year for service with the South African Air Force.

Milkor’s Group Chief Executive Officer, Phuti Jackson Mampa, has expressed that “there are numerous applications in which the Milkor 380 could play a crucial role in enhancing operational capabilities and contributing to the overall success of the South African National Defence Force, the Border Management Authority, and the South African Police Service. The availability of a domestically supported platform that is produced and manufactured in South Africa will enhance operational readiness in supporting troops during missions. We have received significant support from the Department of Defence, the South African Air Force, and Armscor and are confident that South Africa will benefit from this system.”

The company’s Communications Director, Daniel du Plessis, remarked, "This is the largest drone ever produced on the African continent. Only a limited number of companies globally can design and manufacture a device of this magnitude. This development provides an opportunity for South Africa and other nations on the continent to leverage this technology for their defence and security forces."

The Milkor 380 UAV is recognised as the largest unmanned aircraft constructed in Africa, featuring an 18.6-meter wingspan and a maximum take-off weight of 1,300 kg. Paired with its 135-hp four-stroke, four-cylinder turbocharged Rotax 915iS engine, the Milkor 380 is comparable to the US GA-ASI Predator.

The airborne platform is intended for military export customers as well as for applications in public, border control, and conservation as well as anti-poaching operations. Milkor aims for this aircraft to serve as competition to Türkiye’s prominent Bayraktar TB-2 and the TAI Anka and Akinci drones, which have achieved considerable success in sales, particularly among nations that cannot acquire the latest US Unmanned Combat Aerial Vehicles (UCAVs).

A Milkor office in the United Arab Emirates, named Milkor UAE, was formally established at IDEX 2021, coinciding with the introduction of what was then referred to as the Milkor UCAV by the Minister of State for Defence Affairs, Mohammad Ahmad Al Berardi.

Currently, the production capacity for the Milkor 380 is established at eight systems per year, with the sixth airframe in production. Plans are in place to double the output to sixteen systems per year by the beginning of 2026. This expansion is supported by the company’s skilled engineering workforce, which includes approximately 350 employees at the Cape Town facility, 80% of whom are engineers. The company anticipates further growth and plans to recruit an additional 150 employees in the forthcoming year.

A significant challenge facing the Milkor 380 is the absence of clear regulatory frameworks governing large UAVs within South Africa. Milkor is actively collaborating with the South African Air Force, Armscor, and the Department of Defence to obtain military-type certification for the UAV. Attaining this certification is critical for the operational success of the Milkor 380.

Thoughts

The Milkor 380 succeeds the smaller, hand-launched MA18 portable unmanned aerial vehicle (UAV) and the smaller, T-tailed MA80, as well as the similarly named MA380 UAV, which also features a T-tailed configuration. In contrast, the new UAV presents a design that is reminiscent of the United States General Atomics Aeronautical Systems, Inc. (GA-ASI) Predator, characterised by a V-tail (or more accurately, a Y-shaped tail augmented by a ventral tailfin that enhances the dihedral tailfins).

Milkor (Pty) Ltd, in conjunction with its Polish subsidiary Milkor Polska Sp.zo.o., has entered a Memorandum of Understanding (MoU) with Germany’s Aerodata AG, aimed at collaboration in the domain of unmanned airborne maritime surveillance. This development may indicate the consideration of a maritime version of the Milkor 380.

Milkor Integrated Systems, located in Cape Town, functions as the primary facility for the development and production of the Milkor 380. This facility is responsible for the integration of all subcomponents, including avionics, sensor suites, and the airframe itself.

Milkor takes significant pride in its in-house composite manufacturing capabilities. The prototypes were initially produced using a composite lay-up process; however, production methods have evolved to incorporate more advanced techniques, such as vacuum infusion resin manufacturing, which facilitates enhanced precision and durability in the final products.
