Note
LTAMDS program will develop nascent capability and support Army demonstration and test initiatives to increase integrated offensive and defensive capability across
warfighter functions and multiple domains.
A. Mission Description and Budget Item Justification
This funding line is directly aligned to the Army Air and Missile Defense Modernization Priority. Lower Tier Air Missile Defense Sensor (LTAMDS) program will provide
the required sensing capabilities, surveillance and fire control in the lower tier portion of the Army Integrated Air and Missile Defense (IAMD) of the ballistic missile
defense battlespace. The acquisition program competitively selected the LTAMDS prime vendor in 1st Quarter (Q) Fiscal Year (FY) 2020 to build six Prototype sensors
under the authority of Section 804 Rapid Prototyping. The sensor/radar set (RS) replaces the baseline PATRIOT RS (AN/MPQ-65A) in an IBCS enabled PATRIOT
Battalion mitigating the risk associated with threat changes while also addressing growing obsolescence and increasing Operational & Support (O&S) cost. The
LTAMDS capability addresses critical capability gaps, modernizes technology, and increases reliability and maintainability. The LTAMDS capability increases sensor/
radar performance to maximize the inherent PATRIOT Advanced Capability (PAC-3) Missile Segment Enhanced (MSE) Interceptor capabilities to engage threats.
LTAMDS will provide 4 prototype sensors under Urgent Materiel Release (UMR) in FY23. Pre-Planned Product Improvement (P3I) efforts will bridge known capability
gaps leading to an Initial Operational Test and Evaluation (IOT&E) in FY26 and Full Rate Production in FY27. FY2023 UMR tasks include acquiring remaining targets for
testing, completing Contractor Verification Test, Developmental Test and Evaluation, and Operational Assessment. P3I tasks include acquiring up to two P3I prototypes,
targets for testing, and additional capability development. Other FY2023 tasks include Large Tactical Power System (LTPS) development and integration activities
with the Integrated Air and Missile Defense Battle Command System (IBCS) and PATRIOT family of interceptors (PAC-2 GEM-T, PAC-3, PAC-3 MSE) in support of
Integrated Fires and Multi-domain Operations.
The total cost of the LTAMDS Middle Tier of Acquisition effort is $1,524.8 million RDT&E from FY19 to FY24.

A. Mission Description and Budget Item Justification
The Lower Tier Air and Missile Defense Sensor (LTAMDS) satisfies the Warfighter's capability requirements in the Integrated Air and Missile Defense domain. The
program provides the required sensing capabilities in the lower tier portion of the air and missile defense battlespace and expands the battlespace for the PATRIOT
Advanced Capability (PAC-3) Missile Segment Enhancement (MSE) interceptor, and will be upgradable for the Future Interceptor. The Army Requirements Oversight
Council (AROC) approved LTAMDS requirements in April 2016. The Army competitively selected the LTAMDS, which will counter air and missile defense threats using
state-of-the-art technology, while reducing operating and sustainment costs, mitigating obsolescence, and increasing reliability and maintainability .
LTAMDS will provide 4 prototype sensors under Urgent Materiel Release (UMR) in FY23. Pre-Planned Product Improvement (P3I) efforts will bridge known capability
gaps leading to an Initial Operational Test and Evaluation (IOT&E) in FY26 and Full Rate Production in FY27. LTAMDS Fiscal Year (FY) FY2023 funding for UMR
include acquiring remaining targets for testing, completing Contractor Verification Test, Developmental Test and Evaluation, and Operational Assessment. P3I tasks
include acquiring up to two P3I prototypes, targets for testing, and additional capability development such as non-cooperative target recognition and electronic protect.
Other FY2023 tasks include Large Tactical Power System (LTPS) development and integration activities with the Integrated Air and Missile Defense Battle Command
System (IBCS) and PATRIOT family of interceptors (PAC-2 GEM-T, PAC-3, PAC-3 MSE) in support of Integrated Fires and Multi-domain Operations.
The total cost of the LTAMDS Middle Tier of Acquisition effort is $1,524.8 million RDT&E from FY19 to 1QFY24.

Remarks
D. Acquisition Strategy
To enhance the Warfighter's lethality, survivability, and combat effectiveness, the Army used full and open competitive processes within Other Transactions Authority
(OTA) agreements for rapid prototyping, qualification, and initial fielding efforts to meet the intent of FY 2018 National Defense Authorization Act (NDAA) Congressional
language. Middle Tier Acquisition (MTA) rapid prototyping approach (Section 804, FY 2016 NDAA) authorities were leveraged in conjunction with the OTA to facilitate
and accelerate traditional defense contractor involvement, cost sharing arrangements, and accelerate schedules. A FedBizOpps (FBO) announcement and subsequent
LTAMDS Industry Day generated government-contractor dialogue, provided contractor cost and schedule estimates, verified industry technology and manufacturing
readiness, and informed stakeholders on design approaches and potential materiel solutions. This approach also provides senior leader decision points along the
way to make informed decisions based on industry ability to meet threshold requirements. The Sense-Off conducted in 3rd Quarter (Q) FY 2019, along with industry
proposals, enabled the selection of an LTAMDS single vendor with the subsequent award of the OTA Agreement in 1Q FY 2020.
The MTA LTAMDS program will produce six prototypes and conduct contractor and Government testing through 3Q FY 2023. An LTAMDS Operational Assessment will
be conducted 3Q FY 2023 during an Army Integrated Air and Missile Defense (IAMD) Integrated Fires Test Campaign event. Upon successful prototype demonstration,
four prototypes will be immediately provided under Urgent Materiel Release (UMR), which includes the 400kW Mobile Electric Power (MEP)-Power Unit (PU)-810 as an
interim power source. The LTAMDS program will then transition from a MTA program to a Major Capabilities Acquisition (MCA) Program with entry at Milestone C in 1Q
FY 2024.
The LTAMDS Pre-Planned Product Improvement (P3I) efforts will bridge known capability gaps in the UMR prototypes and will include necessary qualification testing
to comply with Type Classification and Full Materiel Release requirements. In addition, development of the 500kW Large Tactical Power System (LTPS) begins with
the release of the Request for Prototype Proposal in FY 2022. The LTPS is a critical component of the LTAMDS sensor, allowing LTAMDS to support the full kinematic
range of the PAC-3 Missile Segment Enhancement (MSE) interceptor.
On 11 August 2020, the LTAMDS Long Term Power General Officer Steering Committee directed the Expeditionary Energy & Sustainment Systems (E2S2) Project
Office to pursue a new Army standard generator that would meet LTAMDS power requirements. The Search, Track, Acquire, Radiate, Eliminate (STARE) Project
Office partnered with the E2S2 Project Office to develop and deliver the LTPS during the LTAMDS Production and Deployment Phase. The E2S2 Project Office will
release a Request for Prototype Proposal in 2Q FY 22. LTAMDS will provide approximately $57M for Research, Development, Test and Evaluation (RDT&E) funding
across FY 2022-2025 for LTPS development and testing. A two-vendor prototyping effort begins in FY 2023, producing eight prototypes to conduct developmental
testing (DT) and operational testing (OT) sufficient to award the single-vendor production contract planned in FY 2025. The schedule outlines a two-vendor test-off and
single-vendor down-select process resulting in prototype selection in 2Q FY 2024. LTAMDS will conduct a combined DT/OT event in FY 2025 to validate LTAMDS
performance functionality using prototype LTPS as the threshold power source. The first four LTPSs are projected for delivery 1Q FY 2026 to support LTAMDS New
Equipment Training, Collective Training, and Initial Operational Test & Evaluation (IOT&E). A Full Rate Production decision is anticipated in FY 2027, subsequent to the
Full Materiel Release.

LTAMDS is a component of an integrated fires development effort that includes survivability, resiliency, and effectiveness improvements against advanced threats from
near-peer adversaries. This effort includes integration with an evolving common fires mission command, common development tools and processes, and annual test
and evaluation to provide data supporting program assessments and progress toward closure of performance gaps.
