Integrated Air and Missile Defense Battle Command System

The IBCS program is part of the Army's Integrated Air and Missile Defense (IAMD) effort.[16][17][18] IBCS aims to create an integrated network of air defense sensors, such as AN/MPQ-64 Sentinel and AN/TPS-80 G/ATOR,[19] AN/MPQ-53, AN/MPQ-65A and GhostEye (LTAMDS) in Patriot missile system,[20] GhostEye MR in NASAMS, AN/TPY-2 in Terminal High Altitude Area Defense (THAAD)[21] and Ground-Based Midcourse Defense (GMD),[20] AN/SPY-1 and AN/SPY-6 in Aegis BMD,[22] and AN/APG-81 in Lockeed Martin F-35 Lightning II,[23] allowing them to interoperate with IBCS engagement control stations.[24] IBCS engagement stations will be able to take fine control of army-fielded air-defense systems like Patriot and THAAD, directing radar positioning and suggesting recommended launchers; naval, aerial and Marine systems will only be able to share either radar tracks or raw radar data with the IBCS network.[20] The Army requires all new missiles and air-defense systems to implement IBCS support.[25]

Northrop Grumman was announced as the prime contractor in 2010; between 2009 and 2020, the Army had spent $2.7 billion on the program.[26][27]

By May 2015, a first flight test integrated a networked S-280 engagement operations center[28] with radar sensor and interceptor launchers. This test demonstrated a missile kill with the first interceptor. By Army doctrine, two interceptors were launched against that missile. By April 2016,[29] IBCS tests demonstrated sensor fusion from disparate data streams,[7]^{: minute 2:28} identification and tracking of targets, selection of appropriate kill vehicles, and interception of the targets,[7]^{: minute 3:29} but the "IBCS software was 'neither mature nor stable'".[29] On 1 May 2019 an Engagement Operations Center (EOC) for the Integrated Air and Missile Defense (IAMD) Battle Command System (IBCS) was delivered to the Army, at Huntsville, Alabama.[30]

In July 2019, the TRADOC capability manager (TCM) for Strategic Missile Defense (SMD) has accepted the charter for DOTMLPF for the Space and Missile Defense Command (SMDC/ARSTRAT).[31][32]

In September 2020 a Joint exercise against cruise missiles demonstrated AI-based kill chains which can be formulated in seconds; one of the kills was by a kinetic projectile fired by a "M109-based" tracked howitzer[46][47] (a Paladin descendant).[48]

The ranges of the IAMD defensive radars, when operated as a system, are thousands of miles. Cross-domain information from ground, air, and space sensors was passed to a fire control system at Project Convergence 2021 (PC21), via IBCS, during one of the use case scenarios.[49] At PC21 IBCS fused sensor data from an F-35, tracking the target, and passing that data to AFATDS (Army Field Artillery Tactical Data System). The F-35 then served as a spotter for artillery fire on ground target data.[50] More than 100 technologies were prototyped in experiments at PC21.[51]^{: minute 34:00}

By August 2020, a second Limited User Test (LUT) at White Sands Missile Range was able to detect, track, and intercept near-simultaneous low-altitude targets as well as a tactical ballistic missile,[52] over several separate engagements.[42][53][26] Army doctrine can now be updated to allow the launch of a single Patriot against a single target.[52][42] By 2021 the Army awarded a $1.4 billion contract to Northrop Grumman for IBCS.[54]

On 24 February 2022 THAAD radar and TFCC (THAAD Fire Control & Communication) demonstrated their interoperability with Patriot PAC-3 MSE missiles; in other words IBCS can engage targets using both THAAD and Patriot interceptors, freed of a siloed solution (THAAD-only / Patriot-only, etc.).[55] For example, in a scenario where a THAAD system has to conserve its All-Up-Rounds, IBCS can calculate which targets are within the reach of its PAC-3 MSE interceptors, and instead fire the PAC-3 interceptors at those targets within range.[55]

IBCS was projected to be at its initial operating capability (IOC) in Fiscal year 2022.[1]^: 42[lower-alpha 1] In January 2018 James H. Dickinson and Richard Formica broached the integration of strategic fires and air/missile defense in the multi-domain task force.^{: min 37:00}[lower-alpha 2][58] IBCS was finally approved for full-rate production in April 2023, after years of delays.[15]

Raytheon's new GhostEye radar (previously Lower Tier Air and Missiles Defense Sensor, LTAMDS)[35] replaces the Patriot AN/SPY-65A radar. GhostEye will be able to feed raw sensor data to IBCS, and it will fit on a C-17 Globemaster.[21][59][60] GhostEye is engineered to operate with much greater sensitivity, improved range and ability to track smaller, faster-moving targets. It uses three fixed 120-degree arrays to seamlessly find, discriminate and track fast-approaching threats using a 360-degree protection envelope. The arrays are overlapping to close "blind spots" and maintain a track if an attacking missile shifts course in flight. GhostEye can detect the precise shape, size, distance and speed of an approaching threat with high-fidelity sensor "pings"; its semiconductor gallium nitride (GaN) emitters allow increased resolution, accuracy, and power efficiency.[61][62][63][Note 1][59][60][64][65][66] The fielding of four LTAMDS radars to a battalion is expected in 2023.[67][68]

The Indirect fire protection capability (IFPC)[69] Multi-Mission Launcher (MML) will have fielded 50 kW lasers on Strykers[70][71] in 2021 and 2022 to two battalions per year.[72] In late FY2024 an integrated test of LTAMDS, IFPC, and IBCS is planned.[73][74]

Although on 21 August 2019 the Missile Defense Agency (MDA) cancelled the $5.8 billion contract for the Redesigned kill vehicle (RKV),[75][76][77][24] the Army's 100th Missile Defense Brigade will continue to use the Exo-Atmospheric Kill Vehicle (EKV). The current Ground-based Midcourse Defense (GMD) programs continue per plan, with 64 ground-based interceptors (GBIs) in the missile fields for 2019 planned. Command and Control Battle Management and Communications (C2BMC), was developed by the Missile defense agency (as a development organization) and is integrated with GMD, as demonstrated by FTG-11 on 25 March 2019.[78]^: 15:00 By March 2021, the decision to approve further development of the Next Generation Interceptor is on the agenda for the 35th Deputy Secretary of Defense Kathleen Hicks. Hicks has extensive background in defense modernization; the 28th Secretary of Defense Lloyd Austin has recused himself from acquisition matters.[79][80]
