Feasibility Study of Possible UAS Projects for a Small Armed Forces

The short paper studies the feasibility (required resources, competency, and data) of building some UAS capabilities referring to efforts invested in similar capabilities in other countries. First section provides the essential requirement for development of autonomous vehicles. Second section gives a quick overview in trends for unmanning intentions. Third section provides some references and proposes options for a small armed force without a support of strong national defence industry.

1. Requirements for Autonomous Vehicle Development

Typically, the development of autonomous systems requires the following process:

1. Creation of a generative adversarial network (GAN)  that can learn from data extracted from live or simulated combat engagements taking place in a relatively stable environment (air or subsurface)
2. Data captured from combat engagement or created in a synthesised game
3. Computer performance to run a high number of simulations to teach the GAN
4. Platform to take the learned AI “driver” to a real environment and start testing and continue learning
5. Feedback loop, re-engineering of GAN, and data bias-removing function to proceed with teaching and improving the performance of the autonomous function.

Furthermore, the following functions or components are required to gain autonomous  features on a platform:

• Sense to gather information about engaging entities and their environment
• Perceive and understand the collected data
• Decide to optimise action based on possible scenarios and their outcome
• Act as control of all physical and logical entities required for impact. 

2. Current Trends in Unmanned Vehicles Development

An advanced autonomous unmanned system is destined to evolve toward low manual intervention, high autonomy, and high intellectualisation, no matter whether it is for military or civilian use. 

3. Examples of Military Autonomous Systems and Required R&D Investments

The following table provides examples from different military autonomous/semiautonomous systems, their development efforts, and options for a small armed force to proceed with similar capability.

UAS Capability	Reference	Investments and time	Options for a small armed force

Remote-controlled driving, autonomous navigation ability along a given route.[10]	2015 prototype 2017 weapon system integration 2019-2020 in operation 2020 sold to 11 countries 2021 EU iMUGS-project builds a standard UGV solution with $32,6 M[11]	1. Acquire the Milrem Intelligent Function Integration Kit (MIFIK) and start implementing it on an existing platform 2. Acquire THeMIS UGVs for tactical development and seek possibilities to join the iMUGS
Unmanned Air Vehicle	Autopilot any aircraft: China refurbished their old fighter jets with unmanned kits and made them multipurpose UAVs[12]	2013 first indications 2021 Won simulated dogfights[13] 2021 seen readiness for SEAD operation[14]	1. Cooperate with PLA to develop “Intelligence Victory” air combat AI 2. Contract a Remotely Piloted Aircraft System provider[15] and build the core system.
Unmanned Combat Air Vehicle	Swarming attack copter: The Golden Eagle 150B Swarm drone is an unmanned attack aircraft manufactured by China North Industries Group.[16]	2017 IDEX as 500 artillery fire control 2018 AirShow China 500 with air to ground missiles[17] 2020 150B with swarming features carrying bomblets[18]	1. Acquire MOTS from China and deploy 2. Build own capability using Drone racing, FPV, sports[19]
Suicide Combat Air Vehicle	Air-to-Ground munition: The AeroVironment Switchblade is a miniature loitering munition that locks onto and tracks a target once selected.[20]	2011 prototype 2012 deployed in ISAF 2015 unarmed variant 2020 anti-armour variant Development est. $10M, an M300 costs est. $6000[21]	1. Acquire MOTS products and deploy with PG to replace Artillery, Helicopter, and CAS support.
Unmanned Air Vehicle Logistics	Autonomous delivery drone: UAV transport packages, medical supplies, food, or other goods.	2013 concept for rapid delivery[22] 2014 prototypes 2015 Ali Baba started delivery 2016 first fully autonomous delivery in the US 2021 Delivery networks based on UAVs[23]	1. Align with regulations, buy COTS drones, and start delivering small goods[24]
