US FY2026 Budget Proposal Seeks KC-135 Stratotanker Drone Launcher Upgrades to Enhance Aerial Tanker Protection

Originally developed in the 1950s, the KC-135 Stratotanker may soon undergo a significant transformation aimed at improving its resilience in increasingly contested airspaces. According to reporting from The War Zone and confirmed in the FY2026 US Air Force budget request published in June, the service is exploring the integration of what is known as a Drone Delivery Mechanism (DDM), an onboard system designed to deploy small unmanned aerial vehicles (UAVs) to bolster the protection of its air-refueling fleet. This initiative underscores a growing emphasis on extending the relevance of legacy aircraft by adapting them to meet modern operational demands in high-threat environments.Follow Army Recognition on Google News at this link

The envisioned Drone Delivery Mechanism would modify the KC-135’s structure, notably its aft door, with a Common Launch Tube system capable of releasing small air-launched drones such as the Coyote or Altius-600. These drones could carry out a variety of tasks, including surveillance, reconnaissance, decoy missions, or electronic warfare, providing tanker crews with new options for threat detection and countermeasures far beyond conventional defensive tools like chaff or flares. As detailed by Army Recognition, this initiative aims to give air-refueling aircraft greater situational awareness and stand-off capabilities, which are increasingly vital in regions where long-range air defense systems pose a major threat.
The KC-135 has served as the backbone of the Air Force’s aerial refueling operations since the Cold War, and the drone launcher concept represents one of the most forward-looking upgrades for this platform to date. Early flight demonstrations of the DDM reportedly took place during fiscal year 2024, laying the groundwork for its inclusion in the FY2026 budget proposal. By pursuing a formal Program of Record, the Air Force hopes to build on lessons learned from current high-threat environments, including contested airspaces over Eastern Europe and the Indo-Pacific, where large support aircraft remain vulnerable to advanced anti-access systems.
Unlike passive defensive upgrades implemented in the past, such as the Large Aircraft Infrared Countermeasures (LAIRCM) system used to disrupt incoming missiles, the DDM concept provides tankers with a more active layer of protection. By launching drones that can scout, jam, or distract potential threats, the KC-135 could gain a capability that has previously been tested on bombers like the B-52 but not operationally deployed on refueling aircraft. This could enable more flexible and survivable tanker operations in areas where adversaries employ sophisticated air defense networks.
If fully developed, this new drone deployment ability would also signal a broader commitment to protecting high-value enablers that sustain combat operations at long ranges. As potential adversaries continue to expand their air denial capabilities, the ability of tankers to safely operate near the battlespace becomes a key factor in maintaining air power projection. For allied forces and US partners in regions such as NATO’s eastern flank or the Indo-Pacific, the adaptation of the KC-135 highlights Washington’s resolve to close critical gaps in force protection for support assets.
Financial documents confirm that the DDM is now referenced in the FY2026 Air Force budget request, although full-scale procurement and integration will depend on further funding and testing. The Air Force Life Cycle Management Center and Air Mobility Command are reportedly collaborating to oversee the potential transition of this concept into an established program. While the KC-135 remains a workhorse, the lessons learned through this effort could eventually benefit newer tankers like the KC-46A Pegasus, ensuring that future air mobility platforms remain resilient in contested environments.
By modernizing a decades-old aircraft to meet the challenges of modern warfare, the KC-135 drone launcher project illustrates how the US military is rethinking manned-unmanned teaming to protect vital support operations. If the initiative moves forward, it could redefine aerial refueling survivability and strengthen the Air Force’s ability to sustain operations in areas where aerial dominance is no longer guaranteed.
