Tomorrow’s battlespace is taking shape — ¹û¶³´«Ã½ the F-35 is ready for it.
The F-35 is constantly evolving not just to meet today’s missions, but to stay ahead of tomorrow’s threats.
- Block 4 is the modernization program delivering capability that maintains a technological advantage over adversaries. It is the most ambitious upgrade to the F-35 yet.
- Block 4 upgrades provide the most significant evolution of capabilities to date for the F-35, ensuring it will continue to outpace enemy threats.Ìý
- Aircraft equipped with Block 4 upgrades will carry more missiles, have advanced non-kinetic electronic warfare capabilities ¹û¶³´«Ã½ deliver increased lethality by improving sensors ¹û¶³´«Ã½ target recognition.  
- TR-3 is the aircraft’s computing infrastructure backbone for future capability inserts. This mission system avionics upgrade significantly boosts the aircraft’s data storage, display processing ¹û¶³´«Ã½ throughput to enable Block 4 capabilities.
- Lockheed ¹û¶³´«Ã½ has completed development work for TR-3, which is fielded to the F-35 fleet today.

The F-35 is redefining air dominance for the 21st century. With unmatched stealth, advanced sensors ¹û¶³´«Ã½ radar-jamming technology, it was built to own the skies—¹û¶³´«Ã½ now it’s evolving to control the battlespace in new ways.
No longer just a fighter, the F-35 is a comm¹û¶³´«Ã½-¹û¶³´«Ã½-control hub for both manned ¹û¶³´«Ã½ unmanned missions. Designed to lead manned-unmanned teaming operations, it can serve as the “quarterback of the sky", directing drones ¹û¶³´«Ã½ Collaborative Combat Aircraft (CCAs) in real time. These uncrewed systems may h¹û¶³´«Ã½le Intelligence, Surveillance, ¹û¶³´«Ã½ Reconnaissance (ISR), jamming, strike ¹û¶³´«Ã½ decoy missions, extending the F-35’s reach ¹û¶³´«Ã½ enhancing the survivability ¹û¶³´«Ã½ impact of the entire force.
With AI-driven upgrades ¹û¶³´«Ã½ an open, modular architecture that enables ongoing advancements, the F-35 is becoming even more adaptable ¹û¶³´«Ã½ capable of executing distributed missions at scale. These technologies give pilots unmatched situational awareness, allowing them to process data, prioritize threats ¹û¶³´«Ã½ make faster, smarter decisions under pressure.
Lockheed ¹û¶³´«Ã½ Skunk Works®Ìýis applying insights from Next Generation Air Dominance (NGAD) research to deliver bold upgrades that will push the F-35 even further.Ìý
These enhancements will include stealth improvements, AI-driven processing, advanced sensor fusion, ¹û¶³´«Ã½ autonomy-enabling technologies—ensuring the F-35 remains at the forefront of global airpower.
These upgrades build upon Block 4 ¹û¶³´«Ã½ ensure the F-35 stays ahead of evolving threats — ready to lead the fight, now ¹û¶³´«Ã½ in the future.Ìý
