Marines Have 6 F-35s Without Radars; USAF Will Get Some Too

Executive Summary

The F-35 program is experiencing radar delivery delays: the F-35 Joint Program Office is accepting aircraft delivered without radars (six Marine Corps F-35Bs have already been delivered with ballast in place of radars) because of delays in the AN/APG-85 radar system from Northrop Grumman. Air Force and Navy variants are expected to follow later this year. The event highlights a program-management and supply-chain disruption centered on radar and defense-electronics subsystems that directly affects the F-35 Lightning II Program and the prime/subcontractor production and delivery cadence.

Contractors across the listed market segments should treat this as a medium-severity, cross-cutting supply-chain and schedule risk with both downside (performance, schedule, and potential contractual/earnings impacts for primes and subcontractors) and upside (demand for integration, retrofit, test, and sustainment activity). Companies that support radar systems, defense electronics, aircraft integration, and supply-chain resilience have near-term windows to offer mitigation services, rapid-install capabilities, testing/validation support, or alternative sourcing strategies to program offices and primes.

Impact Matrix

Agencies named in inputs include DOD, Department of the Navy, United States Marine Corps, Department of the Air Force, and the F-35 Joint Program Office; vehicle context includes the F-35 Lightning II Program, IDIQ (Indefinite Delivery/Indefinite Quantity) contracts for aircraft production, and Defense Production Act contracts.
• Timeline: Six Marine Corps F-35Bs already delivered; Air Force and Navy variants will follow later this year.
• Action Required: Monitor communications from the F-35 Joint Program Office and service program offices; assess contract performance clauses and schedule risk exposure; prepare capability briefs for government stakeholders outlining mitigation services.
• Competitive Edge: Build rapid response offerings focused on program schedule recovery, interface verification, and government-facing advisory support to position for tasking when solicitations or contract modifications are issued.

Aerospace Manufacturing

• Risk Level: Medium
• Opportunity: Specific opportunities TBD pending solicitation language. NAICS codes in tags include 336411, 334511, 334220, 541330, 541712 and vehicle context includes the F-35 Lightning II Program and IDIQ contracts for aircraft production.
• Timeline: Six Marine Corps F-35Bs already delivered; Air Force and Navy variants will follow later this year.
• Action Required: Review production schedules and supplier lead times for radar-related integration; evaluate capacity to offer retrofit or temporary installation services; validate supplier qualification and traceability for avionics and electronic components.
• Competitive Edge: Differentiate through demonstrated supply-chain redundancy and rapid retrofit/installation cell capabilities for avionics/radar subsystems.

Military Aircraft

• Risk Level: Medium
• Opportunity: Specific opportunities TBD pending solicitation language. Vehicle context includes the F-35 Lightning II Program.
• Timeline: Six Marine Corps F-35Bs already delivered; Air Force and Navy variants will follow later this year.
• Action Required: Coordinate with primes and the JPO on aircraft readiness and fielding timelines; prepare maintenance, test, and certification plans for post-radar-installation activities.
• Competitive Edge: Offer turnkey installation, flight test support, and accelerated certification packages that minimize aircraft downtime once radars become available.

Radar Systems

• Risk Level: High
• Opportunity: Specific opportunities TBD pending solicitation language. The Summary identifies the AN/APG-85 radar system (Northrop Grumman) and the F-35 Lightning II Program context.
• Timeline: Six Marine Corps F-35Bs already delivered; Air Force and Navy variants will follow later this year.
• Action Required: For radar-system suppliers and integrators, prioritize supply-chain mitigation, schedule recovery planning, and interface verification with aircraft integrators; prepare to support retrofit installs and system acceptance testing.
• Competitive Edge: Demonstrate rapid qualification and integration procedures, spare-parts provisioning, and field-install teams to accelerate insertion when hardware availability resumes.

Electronic Warfare

• Risk Level: Medium
• Opportunity: Specific opportunities TBD pending solicitation language. Vehicle/program context includes the F-35 Lightning II Program.
• Timeline: Six Marine Corps F-35Bs already delivered; Air Force and Navy variants will follow later this year.
• Action Required: Assess impacts to EW integration timelines and testing windows; coordinate with radar and avionics teams to ensure EW suites remain interoperable after radar installation.
• Competitive Edge: Offer combined radar/EW interface validation and system-level test services that reduce rework after radar installs.

Defense Electronics

• Risk Level: High
• Opportunity: Specific opportunities TBD pending solicitation language. NAICS codes from tags apply to firms in electronics and systems integration.
• Timeline: Six Marine Corps F-35Bs already delivered; Air Force and Navy variants will follow later this year.
• Action Required: Reassess component lead times, compliance readiness, and quality documentation for avionics subsystems; engage primes to present mitigation options.
• Competitive Edge: Emphasize component traceability, supplier diversity, and expedited production lanes for critical avionics assemblies.

Supply Chain Management

• Risk Level: High
• Opportunity: Specific opportunities TBD pending solicitation language. Program context includes the F-35 Lightning II Program and the named contractors in the Summary.
• Timeline: Six Marine Corps F-35Bs already delivered; Air Force and Navy variants will follow later this year.
• Action Required: Conduct supply-chain risk assessments focused on radar suppliers; prepare alternate sourcing and inventory strategies; propose subcontracting or partner arrangements to primes and program offices.
• Competitive Edge: Offer proven supply-chain resilience programs (e.g., dual sourcing, surge capacity, inventory mirroring) and business-continuity services tailored to high-value aircraft programs.

Cross-Segment Implications

• Radar Systems and Defense Electronics are primary fault lines: delays in AN/APG-85 production propagate directly into aircraft delivery acceptance, flight test schedules, and operational unit readiness in the Military Aircraft and Aerospace Manufacturing segments.
• Supply Chain Management is a central enabler: failures or delays at radar suppliers create ripple effects across manufacturing, integration, testing, and sustainment lines; mitigation options (alternate suppliers, accelerated manufacturing, retrofit teams) will be sought by primes and program offices.
• Electronic Warfare and Radar Systems integration work together: any timeline slip for radars increases risk that system-level EW testing and certification will be deferred, creating consolidated risk for aircraft mission capability deliveries.
• Defense (government stakeholders) and the F-35 Joint Program Office will likely drive contractual and schedule remediation; primes and subcontractors should prepare for requests to propose recovery plans or scope changes.
• Compliance and contracting surfaces (ITAR (International Traffic in Arms Regulations), DFARS (Defense Federal Acquisition Regulation Supplement), CMMC (Cybersecurity Maturity Model Certification), NIST 800-171 (NIST Special Publication 800-171), EAR) referenced in tags may shape which suppliers and integrators are eligible for rapid-response work, so contractors should confirm compliance posture as part of any rapid-mitigation offering.
