Offensive Anti-Surface Warfare Weapon Dev

Abstract

Offensive Anti-Surface Warfare (OASuW) is an offensive weapon system that is a vital component of the Joint Force Anti-Surface Warfare capability and incorporates new and emergent technologies to support an increased offensive strike capability utilizing multiple weapons. OASuW Increment 2 is a national imperative to maturing hypersonic capabilities. The program will provide the Navy a necessary weapon to address evolving long range high speed threats from near peer competitors. The OASuW program is part of the Navy's Long Range Fires (LRF) approach to address advanced threat capabilities in the Anti-Access/Area-Denial (A2AD) environment. LRF solutions enable individual system capabilities to be leveraged across an effects chain, placing the full spectrum of tactical capability in the hands of the warfighter. LRF solutions that push engagement distances beyond the launch platform's radar horizon and allows the U.S. Navy to operate in, and control, contested battle space in littoral waters and A2/AD environments are increasingly critical as more and more scenarios require compressed and coordinated fire control timelines. OASuW strategy pursues capability across multiple weapon systems to enhance warfighting capabilities. Project 3343 - The Department of the Navy is developing Offensive Anti-Surface Warfare Increment 2 (OASuW Inc 2), also known as Hypersonic Air-Launched OASuW (HALO), to address weapon system requirements based on the OASuW Analysis of Alternatives (AoA). OASuW Inc 2/HALO will be a carrier-suitable, higher-speed, longer-range, air-launched weapon system providing superior Anti Surface Warfare capabilities. The program is part of the Navy's Long Range Fires investment approach to meet objectives of the National Defense Strategy. As a key component of this strategy, OASuW Inc 2/HALO will address advanced threats from engagement distances that allow the Navy to operate in, and control, contested battle space in littoral waters and Anti-Access/Area Denial (A2/AD) environments. To the maximum extent possible, the Navy will leverage technology being matured in the Science and Technology (S&T) and rapid prototyping arenas to support aggressive schedule execution. The OASuW Inc 2/HALO program will progress through a competitive technical maturation and design development period which will provide the foundation for an Engineering, Manufacturing and Development contract. Department approved requirements are documented in a Service Level Capability Development Document. In order to counter the evolving near-peer threat capability, OASuW Inc 2/HALO has been accelerated to achieve Early Operational Capability (EOC) in FY 2029. Project 3466 - The LRASM C-3 program is established to improve OASuW and incorporate a long range strike capability into the Navy's arsenal derived from the Navy's AGM-158C-1 LRASM and the Air Force's AGM-158 JASSM-ER. The Navy will integrate an AGM-158 derived weapon onto F/A-18 E/F aircraft. This funding line resources requirements for Navy increased LRASM capabilities and strike mission integration by upgrading the existing AGM-158C product to respond to rapidly changing threats. Project 3337 - Due to emerging threats, the fleet issued an Urgent Operational Needs Statement (UONS) that identified a capability gap for a long-range anti-ship missile to be filled by 2018. Directly supporting this UONS and significantly reducing Joint Force warfighting risks, the U.S. Navy initiated OASuW Increment 1 (OASuW-1), which leverages the Defense Advanced Research Projects Agency (DARPA)/Office of Naval Research Long Range Anti-Ship Missile (LRASM) demonstration program to deliver an Early Operational Capability (EOC) in the required timeframe. LRASM fills the most urgent air-launched capability gap to complement existing ASuW weapon systems and positions the Department of Defense to address evolving surface warfare threats. LRASM is integral to realizing the National Defense Strategy of combat-credible military forces to deter war, protect the security of our nation and to enable the Joint Force to win should deterrence fail. The development and acquisition of LRASM has been structured to be fielded at a pace relevant to maintain overmatch against long-term strategic competition. Specifically, LRASM directly contributes to building a more lethal force and is a critical enabler for joint lethality in contested environments; deterring adversaries from aggression; ensuring common domains remain open and maintaining favorable regional balances of power. The more capable LRASM 1.1 capability improvement efforts conclude with FY 2023 funding. Budget Item Justification: This program is funded under ADVANCED COMPONENT DEVELOPMENT AND PROTOTYPES because it includes all efforts necessary to evaluate integrated technologies, representative models or prototype systems in a high fidelity and realistic operating environment.
