ISEA NEN: Contract at a Glance

Description of ISEA NEN Requirements

Support for Code 41260, the Shore Networks Branch; responsible for the design, development, accreditation, integration, modernization, sustainment, and Life Cycle Support of shore networks and network service solutions for Navy and Joint Department of Defense (DoD) units worldwide. The contractor must deliver services across ten areas:

• Integrated Project Team and Project Management
• Sustainment Engineering Support (including Network Response and Systems Engineering)
• Technical Sustainment Support, including 24/7 on-call and on-site troubleshooting worldwide
• Integrated Logistics Support
• Configuration Management
• Certification and Accreditation
• System Implementation and Upgrade, including BESEP and IDP development
• Enterprise Applications Support
• Work Baseline Software Configuration Support
• Tier IV OCONUS Support at NCTS Naples, NCTS Bahrain, NCTS Far East (Yokosuka), and outlying sites

Three Key Areas the Government Will Evaluate

The market survey identifies three capability areas that will drive the government’s small business assessment and inform the formal solicitation:

• Key Area 1: Sustainment Engineering on Naval Enterprise Networks — specifically Network Response Group (NRG) execution and Network Systems Engineering support.
• Key Area 2: Technical support on NEN — specifically documented test procedures and Verification and Validation (V&V) support.
• Key Area 3: Tier IV OCONUS Support — specifically the RFC process, legacy network replacement at multiple OCONUS sites, and 24/7 worldwide support.

Bid Risks to Assess Before You Commit

• Seaport NxG eligibility: Large businesses are explicitly excluded, and only active MAC holders may respond. Confirm your MAC status immediately; teaming with a holder is the only path for non-MAC firms.
• Size standard: NAICS Code 541330, with the Military exception, carries a $47M size standard. Verify revenues, including affiliates, before committing to a pursuit.
• Incumbent strength: SAIC holds the current task order (N6600122F3509). Displacing an established incumbent on a mission-critical Navy network program requires a clearly differentiated technical approach and stronger past performance.
• Past performance specificity: The three key capability areas demand NEN-specific experience. Generic DoD IT support will not score competitively against an incumbent with direct NEN history.
• Security clearance depth: All contractor personnel at government facilities require a minimum SECRET clearance. Select positions require TS/SCI with JWICS access; those personnel must also complete the NATO awareness briefing and derivative classification training per the SOW. Know your workforce’s clearance posture before bid day.
• OCONUS complexity: Tier IV support at three named OCONUS Theater Network Operations and Security Centers (TNOSCs), plus outlying ports, demands credible staffing, logistics, and travel compliance plans.
• Subcontracting limits: The Limitations on Subcontracting clause (FAR 52.219-14) applies. The small business prime may not pay more than 50% of the contract value to non-similarly situated entity subcontractors.

What It Takes to Win

• Respond to the market survey by May 11, 2026. Submit up to three corporate experience examples via the government’s Microsoft Forms link, directly addressing the three government-defined key areas. Responses not conforming to the market survey instructions may not be considered.
• Match past performance to the three key areas. Each reference must demonstrate current (within 5 years), relevant NEN or comparable Navy shore network experience. Document CPARS ratings, contract values, and OCONUS performance history.
• Differentiate on Tier IV OCONUS. The NCTS Naples, Bahrain, and Far East requirements involve legacy network replacement, 24/7 on-call support, and overseas travel compliance. A specific, credible OCONUS technical approach with named experience at comparable sites is a decisive discriminator.
• Validate clearances and labor mix. The SOW’s labor categories (Systems Engineers IV and II, Logisticians, and Management Analysts) must be staffed with cleared personnel. Map your workforce against the government’s full-time equivalent (FTE) table before committing.
