Global Aerospace Corporation (GAC) has experience in the design of deep underwater systems operating at depths of down to 6,000 meters. GAC has specific experience in the integration, deployment, and operation of payloads from deep ocean depths. GAC is introducing new approaches to deploy unmanned systems that can provide non-lethal effects or situational awareness over large maritime areas. We have the experience to create underwater systems that can survive for many years under extreme pressures, operate reliably, operate through the water column, and deploy operational systems. Our systems engineering experience is in deep ocean apparatus design, deployment, and mission execution, as well as in pressure tolerant encapsulation systems and communications. We can define and carry out system-level requirements, create conceptual designs, perform underwater testing, develop mission and concept of operations, develop payloads, and perform prototype testing. GAC has carried out independent research and development activities related to the development of, and use of, underwater diver breathing systems including a submersible aircraft project that could be used by Special Operation Forces (SOF) during submerged transit to shore insertion points. GAC personnel have extensive experience in the understanding of the physics and the design of systems that operate in hostile, extreme environments. In particular, the senior engineering staff members have expertise in structural and stability analysis, in the design of life support and buoyancy control systems for manned submersibles, and in the design of critical subsystems including surface propulsion, submerged propulsion, ballast, energy storage, life support, and controls integration.

Upward Falling Payload (UFP)

Global Aerospace Corporation (GAC) is a UFP performer involved in the development of two of the key UFP subsystems: the payload and the riser. In GAC's mission scenario, UFP nodes are deployed years before needed as part of a large, capable UFP network in some distant sea. Each node contains underwater communications hardware, a riser, and a small UAV that can be cued to a desired location. GAC and its R&D partners are developing the Mission Node. The objective of the currently ongoing Phase 2 is to demonstrate a UFP node capable of launching a working payload from a depth of more than 6 km and that meets the UFP metrics.

By exploiting environmental conditions and basic physics, it is anticipated that the riser and the UAV will enable powerful effects with a large influence range at low cost and risk. The technical tasks include mission, effects and concept of operations (ConOps) development; riser development; UAV development; and prototype testing. In the mission, effects and ConOps development task, GAC carried out high-fidelity UAV flight path simulations and detailed mission effects development. For the riser task, GAC carried out the preliminary design and conducted component tests in the lab, test facilities, and at sea and has performed the detailed design and fabricated and assembled the system.

GAC conducted the preliminary design of a submersible aircraft for special operation forces' insertion and extraction. GAC addressed the technical challenges for combined fast amphibious, submersible, and air vehicles capable of transporting four SOF operators with their equipment. The traditional method for insertion and extraction of operators on contested shores involves the use of submarines equipped with special mini-sub dry docks mounted on their backs. During the few hours of transit from the large sub to the insertion point in the mini-sub, the operators are exposed to the environment, which can leave operators cold and exhausted at the start of the mission. Instead, our approach protects the SOF operators in a dry cabin all the way to the insertion point. The system design tolerates submersion and underwater operation, minimizes the needed ballast mass, and key elements like instruments, flight controls, fuel system, and engines are designed to withstand the subsea environment and still operate successfully afterwards.
