Army to re-purpose Navy booster and build road-mobile, deep-strike hypersonic weapon

The Army is launching a Long-Range Hypersonic Weapon program to develop a capability to punch through
contested, anti-access environments - a big-ticket acquisition project that will re-purpose a Navy hypersonic
booster being developed by Lockheed Martin for use on a road-mobile system, giving ground forces a
conventionally armed strategic system for the opening salvos of a major fight. On Oct. 4, the Army presented
secret plans for this new deep-strike weapon to a select industry audience, setting in motion an...

For reference on the intermediate range booster stack:

SSP seeks input from industry to determine if there are sources capable of satisfying its potential requirements
to design two Technology Booster Solid Rocket Motor stages. The booster should use high energy Hazard Class 1.3
propellant, be capable of Intermediate Range, and in the 30 to 40 inch diameter class. The anticipated primary
deliverables are a Technology Booster Design Disclosure, a Performance Analysis and Design Report, a Technology
Booster Demonstration Static Firing Test Plan and associated Post-Test Analysis Report.

The potential booster design, build, and ground test does not reflect any endorsement by the Department of Defense
nor does it reflect any policy considerations that may apply to any given concept (e.g., basing arrangements, treaty compliance, etc.)

From March of 2017; that last chunk on treaty compliance is cute.

Program Targets Innovative Propulsion Solutions for Ground-Based Weapons Delivery System

The joint DARPA/U.S. Army Operational Fires (OpFires) program will soon kick off with three performers awarded contracts to begin work: Aerojet Rocketdyne, Exquadrum, and Sierra Nevada Corporation. OpFires aims to develop and demonstrate a novel ground-launched system enabling hypersonic boost glide weapons to penetrate modern enemy air defenses and rapidly and precisely engage critical time sensitive targets.

OpFires seeks to develop innovative propulsion solutions that will enable a mobile, ground-launched tactical weapons delivery system capable of carrying a variety of payloads to a variety of ranges. Phase 1 of the program will be a 12-month effort focused on early development and demonstration of booster solutions that provide variable thrust propulsion across robust operational parameters in large tactical missiles.

“OpFires represents a critical capability development in support of the Army’s investments in long-range precision fires,” says DARPA’s OpFires program manager, Maj. Amber Walker (U.S. Army). “These awards are the first step in the process to deliver this capability in support of U.S. overmatch.”

The OpFires program will conduct a series of subsystem tests designed to evaluate component design and system compatibility for future tactical operating environments. Phase 2 will mature designs and demonstrate performance with hot/static fire tests targeted for late 2020. Phase 3, which will focus on weapon system integration, will culminate in integrated end-to-end flight tests in 2022.

DESLA Team Successfully Tests Thrust Chamber and Nozzle Technologies Key for Advanced Upper Stage Engine

VICTORVILLE, CA – November 1, 2012 The DESLA Team, which is comprised of Exquadrum, WASK Engineering, and ATK (NYSE: ATK), announce they have successfully conducted testing on a modular thrust chamber design and aerospike nozzle as part of AFRL research efforts. The data gathered on these programs will be leveraged for the Dual Expander Short Length Aerospike (DESLA) engine.

Exquadrum conducted a series of full-scale hot fire tests up to 100 percent chamber pressure on the modular thrust chamber funded under the Deep Throttle Enabling Nozzle Technology SBIR contract at its Adelanto, California test facility. The modular thrust chamber enables modern manufacturing methods that significantly lowers recurring and non-recurring costs, which are necessary to achieve an affordable engine while enhancing overall system performance.

“The successful testing of the modular thruster demonstrates both the performance and significant cost savings this technology provides," said Philip Pelfrey, Executive Vice President for Exquadrum.

Additionally, WASK Engineering has successfully completed baseline performance cold flow testing of a 30 percent length annular aerospike nozzle from sea level to vacuum conditions as part of the Third Generation Reusable Boost (3GRB) Program at the NASA Marshall Space Flight Center Nozzle Test Facility in Huntsville, Alabama. The testing obtained high quality data that validated computer tools and performance predictions which will be used for the DESLA engine.

“The results of this testing effort validated the performance predictions for the nozzle technology we are using for DESLA”, said Wendel Burkhardt, President of WASK Engineering.

The DESLA engine is an advanced, 30,000 pound thrust liquid hydrogen / liquid oxygen upper stage engine intended for the Air Force’s Evolved Expendable Launch Vehicle (EELV) and NASA’s next generation Cryogenic Propulsion System (CPS).

AFRL has awarded Exquadrum a nine month contract to develop a novel upper stage engine cycle. In performance of the contract, Exquadrum will further develop its SLATE dual-bleed expander cycle engine conceptual design and conduct proof-of-concept demonstration testing. The SLATE engine enables lower pump discharge and system pressures for high-reliability and reduced weight.

The goal of the program is to reduce the weight and cost of the upper stage rocket engine while maintaining state-of-the-art performance and increasing reliability, operability, and scalability. Exquadrum’s upper stage rocket engine concept is significantly smaller and lighter than historical engines, is scalable to larger thrust levels, and promises increased stability over any existing conventional thrust chamber of comparable engine size.
