The US Missile Defense Agency (MDA) has achieved a significant milestone in its hypersonic program with the successful completion of the first flight of its Hypersonic Test Bed (HTB). Designed as a unified platform for all hypersonic experiments, the HTB aims to advance the US's hypersonic capabilities.
During the HTB-1 test, the vehicle achieved hypersonic flight, allowing for the collection of valuable data from various internal and external experiments. MDA Director Lt. Gen. Heath Collins described the test as a major success, marking the beginning of a cost-effective platform for conducting hypersonic experiments. "HTB-1 represents a significant step forward in hypersonic testing capability," Collins stated.
The MDA highlighted that the HTB will be crucial in accelerating the development and deployment of hypersonic technologies, enhancing the US's ability to conduct frequent and varied tests. This capability is essential for advancing state-of-the-art technologies that can reliably operate in hypersonic flight conditions, according to Collins.
Collaborating with numerous partners, the MDA aims to use data from these tests to develop advanced capabilities for a comprehensive hypersonic defense system. As the leading agency for hypersonic defense, the MDA is working to outpace the threats posed by the hypersonic advancements of Russia and China.
Both Russia and China have developed multiple hypersonic weapons, placing the US in a position to catch up. The MDA's hypersonic test bed joins a growing array of high-speed flight test devices, providing a versatile platform for various hypersonic experiments. This includes contributions from the Defense Innovation Unit's Hypersonic and High-Cadence Airborne Testing Capabilities program and the Test Resource Management Center's Multi-Service Advanced Capability Hypersonic Test Bed.
While the MDA has not disclosed details about the creators of the HTB, the agency announced that advanced missile tracking satellites captured their first images of the hypersonic flight test. Although the departure time from Wallops Island, Virginia, was not revealed, the agency confirmed that initial reports showed successful data collection from the sensors.
Lt. Gen. Collins mentioned that this first calibration flight is a precursor to another test bed launch later this year. The Hypersonic and Ballistic Tracking Space Sensors (HBTSS) satellites, part of the Space Development Agency's constellation, played a crucial role in tracking the hypersonic flight. These sensors are designed to detect and monitor hypersonic weapons traveling at speeds of Mach 5 or greater.
Currently, there are ten missile-tracking satellites in space, shared between the MDA and the Space Development Agency (SDA). Despite the different development projects for these sensors, the HBTSS medium-field-of-view sensor will be integrated into future SDA spacecraft iterations, enhancing the ability to track dim targets and relay data to interceptors.
Eventually, a constellation of 100 satellites will provide global coverage for advanced missile launches. However, the current limited fleet offers restricted coverage, necessitating careful coordination of satellite monitoring opportunities to ensure they are positioned over test venues and hotspots worldwide.
