The U.S. Army's Indirect Fire Protection Capability (IFPC)

System


Background
Protecting high-value military sites against enemy cruise
missile (CM), unmanned aerial system (UAS), and rocket,
artillery, and mortar (RAM) attacks has long been an
important consideration in protecting military forces. The
2020 Nagorno-Karabakh  Conflict between Armenia and
Azerbaijan and ongoing conflicts in Ukraine and between
Israel and Palestinian militants in the Gaza Strip have
heightened interest in the efficacy of these force protection
systems and highlighted the requirement to protect sites and
other assets from such threats.

According to the Army, the Indirect Fire Protection
Capability (IFPC) System is a mobile, ground-based
weapon  system designed to defeat cruise missiles (CM),
unmanned  aircraft systems (UAS), and rocket, artillery, and
mortars (RAM). IFPC is to consist of a launcher and
interceptors. IFPC is to use the U.S. Army's Integrated Air
and Missile Defense Battle Command System (IBCS) for
mission command  and integrate the AN/MPQ-64 Sentinel
Radar as its sensor. IFPC is intended to protect critical
fixed- or semi-fixed assets, and bridge the gap between
short-range air defense (SHORAD) systems-the Patriot air
and missile defense system, and the Terminal High Altitude
Area Defense (THAAD)   system.

Origins   of  the  IFPC   Program
The Army  initiated the original IFPC program, known as
IFPC Increment 1, in 2004 based on a Multi-National
Force-Iraq Operational Needs Statement. In 2005, the Army
deployed the Land-based Phalanx Weapon System (LPWS)
along with associated radars to Iraq to intercept hostile
rockets, artillery, and mortars (RAM). The Army treated
this as an interim solution and continued developmental
efforts. Concerned with the pace and direction of the
Army's counter RAM  (C-RAM)   development, some in
Congress expressed an interest in acquiring Israel's Iron
Dome  C-RAM   system as an interim solution. In both the
FY2019  National Defense Authorization Act (NDAA) (P.L.
115-232) and the FY2019 Department of Defense
Appropriations Act (P.L. 115-245), Congress directed the
Army  to deploy four batteries-two in 2020 and two in
2023-of  a medium-range air defense system to counter
cruise missiles and other threats. In response to this
mandate, the Army selected Iron Dome as providing the
best value to the Army based on its schedule, cost per kill,
magazine depth, and capability against specified threats.

Because of difficulties integrating the first two Iron Dome
batteries into existing and planned U.S. Army air and
missile defense command and control architecture, the
FY2021  NDAA   (P.L. 116-283) waived the requirement for
the final two Iron Dome batteries. The decision not to adopt


Iron Dome reportedly served as the basis for the Army
initiating the IFPC Increment 2 program.

On September 24, 2021, the Army announced the award of
a three-year prototype Other Transaction Authority
Agreement  (OTA) to Dynetics (a subsidiary of Leidos) for
the development and delivery of 16 launcher prototypes, 60
interceptors, and associated all-up-round magazines for the
Indirect Fire Protection Capability Increment 2. The OTA
was valued at approximately $237.38 million over two and
a half years.

Plans called for prototype development in Huntsville, AL,
and Tucson, AZ, with deliveries to support testing
beginning in the fourth quarter of FY2022. The first IFPC
Increment 2 combat-capable battery was to be available to
the Army in the fourth quarter of FY2023. The Army plans
to make a Milestone C Decision (decision to transition to
procurement) in the second quarter of FY2024 and field the
first IFPC Increment 2 battalion by FY2026.

IFPC   Variants
The Army  is presently developing three IFPC variants, the
Increment 2 Interceptor variant, the High Energy Laser
(HEL)  variant, and the High Power Microwave (HPM)
variant. Each variant is in a different stage of development,
and variants are intended to operate in a complementary
manner.

IFPC  Increment   2 Interceptor Variant
The interceptor variant is to utilize an open architecture
design to enable future missile integration. Reportedly,
Increment 2 can employ the AIM-9X Sidewinder missile
