B2S2 – Better Buying Support Services

The B2S2 contract vehicle supports the Army’s Program Executive Office for Intelligence, Electronic Warfare and Sensors (PEO IEW&S) under its Better Buying Support Services (B2S2) multiple award IDIQ contract vehicle. The B2S2 vehicle will provide SETA-type services to the PEO and its PMs.


SEA-PORT-E provides engineering, technical, programmatic, and professional support services to Department of Navy Sea Systems Command organizations spanning 21 functional areas under an Agency IDIQ.

AMCOM Express

AMCOM Express is a blanket purchase agreement (BPA) program based on the use of GSA federal supply schedules for acquiring advisory and assistance services (including all supervision, labor, incidental materials, and travel). These services may take the form of information, advice, opinions, alternatives, analyses, evaluations, recommendations, training, and technical and management support. AMCOM Express’s sponsor is the U. S. Army Contracting Command, Aviation and Missile Command (AMCOM) under an Agency IDIQ.

S3 - Strategic Services Sourcing Contract

The S3 contract vehicle accommodates a broad range of services that are designed to meet the integrated engineering, business function, and logistic service needs of all Team C4ISR customers. The purpose of the S3 contract is to provide access to multiple prime contractors and subcontractors that perform a broad range of life cycle services required to fulfill varied user needs within the framework of a competitive post award environment. S3 is sponsored by CECOM as an Agency IDIQ.

Software and Systems Engineering Services Next Generation (SSES NexGen)

The SSES NexGen program supports Army systems and software across the entire lifecycle, from development to fielding and operational support. The contract concentrates on providing software-related support in three primary mission areas involving in-theater U.S. forces, business systems, and enterprise-wide components. SSES NexGen is sponsored by CECOM as an Agency IDIQ.

Hardware Open System Technologies (HOST) Conformance Tool

The HOST program is comprised of three phases. HOST defines interfaces to hardware such that interoperability and reprocess of hardware components can be recognized while addressing obsolescence. The contract concentrates on developing a tool to support and automate the verification of hardware conformance. The HOST program is sponsored by NAVAIR as an Agency IDIQ.

Battlefield Systems (BSES)

The BSES program focuses on providing support to new technologies and providing systems and computer engineering resource services to SED; the Aviation and Missile Research, Development, and Engineering Center (AMRDEC); and the Army Research, Development and Engineering Command (USA RDECOM). Contract efforts emphasize on delivering research, development, and engineering technology services for aviation and missile platforms across the lifecycle. BSES is offered on behalf of the U.S. Army Software Engineering Directorate and awarded under OASIS as an Agency IDIQ.

Software Life Cycle Development (SLCD)

The SLCD support will span the entire life cycle of systems for which S3I has responsibility. Life cycle support is defined as the activity necessary to define concepts, define requirements, plan, manage, develop, sustain, modify, improve, test, train, field, and retire systems and system computer resources in a time frame necessary to meet customer needs. Awarded under OASIS as an IDIQ by the Research Development and Engineering Command (DOD Army – AMC).

Hardware in the Loop (HWIL) Aviation Systems

The purpose of the HWIL Aviation Systems is to provide full life cycle support for high fidelity aviation system simulators, HWIL capabilities, and associated test tools. Using these capabilities, and in collaboration with Joint Service agencies, Other Government Agencies (OGAs), and industry, rapidly enable cost effective solutions that facilitate readiness and technological dominance of the U.S. Army’s current and future force. Awarded under OASIS as an IDIQ by the CCDC AvMC and S31 Directorate.

Vertical Lift Consortium (VLC)

The VLC is a collaboration of conventional and unconventional government contractors working with the U.S. government to develop and transition innovative vertical lift technologies to meet the increasing needs of warfighters. Utilizing the VLC Other Transaction Agreement (OTA), allows for multi-level industry collaboration toward speedy execution. Under the VLC OTA, the government, in conjunction with VLC and its non-government members, performs a research and development program designed to create prototype aviation technologies.
