South Africa thinks UAVs are a good idea, except for the fact that they have no pilot in them, can't carry enough ordnance, have complex command and control problems, and other difficulties where air traffic control is concerned.
The SA company Aerosud has an answer to the problem, the AHRLAC (Advanced High-performance Reconnaissance & Surveillance Aircraft). The aircraft is a spiritual successor to the WW1 Vickers Gunbus, wherein the engine is in the rear, leaving the front of the aircraft open for weapons systems and complex radars and sensors, and being able to operate on rough airstrips. It is also similiar to the Vietnam era forward air controller Cessna 0-2A Skymaster, only with much higher performance, and better weapons and avionics. And there will be a human in the pilot's seat.
The AHRLAC is only a 1/4 scale flyer right now, but the first prototype is being built and it will be only 34 feet long, but can crank at over 300mph, while carrying rocket pods and at least one 20mm cannon. Looks to be an interesting home brewed African solution to African Homeland Security problems.
