L3Harris’ Viper Shield is accomplishing critical production milestones. The production hardware configuration is currently in flight testing, and Electromagnetic interference (EMI/EPT) Safety of Flight testing began for its next iteration of software development.
Viper Shield is an advanced electronic warfare (EW) suite that significantly enhances both offensive and defensive capabilities. It is the only EW capability for the F-16 that is fully funded through development. Well into its development cycle, Viper Shield is an excellent and advanced solution for the global F-16 fleet.
Seamless Integration with F-16 Variants
One of Viper Shield's most impressive features is its compatibility with various F-16 configurations. It seamlessly fits into the Block 70/72 new aircraft, as well as the Block 40 and Block 50 F-16 fleets, including D-models, without requiring any redesign.
It can also be integrated into previous F-16 blocks through a podded system, which attaches to an aircraft without requiring extensive internal modifications. The podded system incorporates the same Line Replaceable Units (LRUs), optimizing sustainment while ensuring the same electronic warfare protection regardless of internal or external configuration.
This adaptability puts Viper Shield 3-5 years ahead of its competitors, guaranteeing that L3Harris’ international partners receive the most advanced capabilities.
Robust Funding and Expanding Partnerships
The development of Viper Shield is fully funded and backed by six partner nations, with more expected to join this year.
“This strong financial support and the substantial number of orders underscore the confidence and trust placed in Viper Shield's capabilities,” said Ed Zoiss, President, Space and Airborne Systems, L3Harris. “Our competitors simply cannot match this level of readiness and support for the global F-16 fleet.”
System Performing Under Pressure
Viper Shield production hardware flight testing began in January 2025 with test flight in a single-seat Block 70 F-16.
In addition, environmental testing of production hardware in an anechoic chamber has commenced and will prove Viper Shield’s ability to perform reliably in various operational conditions.
Spiral software development of the all-digital, software-defined system continues, allowing the L3Harris team to test enhancements while also producing hardware for current customers.
In Production and Scaling to Meet Demand
Ushering in the next generation of digital fighter pilot protection, Viper Shield is designed for modern aircraft to defeat advanced threats.
Units have been in production for nearly a year and the team is rapidly scaling to meet customer demands.
L3Harris is on track to deliver Viper Shield production hardware by 2025, with a ramp-up to full production by mid-2026 for the 168 systems currently on contract.
This timeline reflects the company’s dedication to meeting global demands with precision and speed.
