The Mark 39 Attack Drone is an automated defense system of the SLDF based on the (then experimental) F-90 Stingray aerospace fighter. Designed to work in conjunction with the much larger M-5 Caspar SDS drones, the Mark 39 is capable of engaging fighter sized targets which the Caspars are unable to target with their naval size armament.
Like land mines, the drones maintain a passive listening mode and respond to all ships that fail to provide a correct IFF transponder code.
The most notable feature about the Mark 39 is that their sophisticated battle computers are capable of coordinating attacks with other Mark 39 and M-5 units by forming a decentralized computer network, which allows the drones to collectively make tactical decisions. The advantages include preventing overcommitting drones against a single target.
The Mark 39 was very successful and deployed in vast numbers (by the thousands) in areas that did not warrant the deployment of M-5 Caspars, such as deep space naval installations like Camelot Command and planetary systems of minor value. Most of the Mark 39 systems had been destroyed, deactivated or otherwise neutralized by the end of the Second Succession War but some can still found in active service.
