The U.S. Air Force command responsible for air operations on the Korean Peninsula is asking industry for counter-drone systems that have already been used in combat. On Oct. 5, Seventh Air Force (7 AF) posted a request for information on SAM.gov titled "Project Iron Sentry: KTO Joint Point Defense Modernization." KTO stands for the Korean theater of operations. The notice carries solicitation number F3J6AF-27-SS001, and responses are due at 8:00 a.m. Korea Standard Time on Oct. 13.

The notice is short and specific. According to the SAM.gov record, 7 AF "is seeking combat-proven, theater-wide C-sUAS/C-UAS capabilities eligible under the Accelerate the Procurement and Fielding of Innovative Technologies (APFIT) program." The place of performance is South Korea.

Taken alone, it is a market-research notice with an eight-day window. It also comes a few weeks after Air Force leaders said defending their own bases against drones and missiles would become a formal mission, with its own weapon system, its own career field and possibly its own acquisition chief.

What the RFI actually asks for

The SAM.gov listing calls Project Iron Sentry an RFI for market research only, so it is not a solicitation for a contract. The standard disclaimer applies: responding is voluntary, and the government will not pay for the cost of preparing a response.

The notice invites APFIT-eligible parties to submit three items from provided templates, by email to the two Air Force points of contact listed:

  • a Letter of Attestation,
  • a Quad Chart, and
  • a Submission Briefing.

Two phrases in the notice show what the command is looking for. "Combat-proven" suggests concepts and prototypes still on the test range are not what 7 AF is after. "Theater-wide" suggests the command is thinking about coverage across the peninsula, not a single installation. 7 AF is headquartered at Osan Air Base, as DefenseScoop noted in its report on the RFI.

Why APFIT matters here

Tying the RFI to APFIT shapes who can respond. DefenseScoop describes APFIT as a program overseen by the Pentagon's chief technology officer that provides funding to speed up the acquisition of capabilities sought by combatant commands and other Defense Department components. Limiting responses to APFIT-eligible vendors suggests 7 AF wants a route to fielding that is faster than a new program of record. That reading fits the short response window and the "combat-proven" requirement, though the notice itself does not say so.

The threat picture

DefenseScoop placed the RFI against two recent reports about North Korea. The first came from the Wall Street Journal, which reported last month that Pyongyang had started exercises practicing "swarm" operations that combine attack drones with missiles and other weapons. The second came from Reuters, which reported that Ukrainian President Volodymyr Zelenskyy said Russia may have given North Korea jet-powered drone technology.

The 7 AF notice does not cite either report. Neither claim has been independently confirmed in the sources reviewed for this article. Both, however, describe the kind of threat that "theater-wide" counter-UAS coverage is meant to handle.

The bigger shift: point defense becomes a mission

Project Iron Sentry follows a set of announcements at the Air & Space Forces Association's Air, Space & Cyber conference in September.

According to Air & Space Forces Magazine, Chief of Staff Gen. Ken Wilsbach told the audience: "We can no longer treat point defense as a side hustle." He announced a Point Defense Weapon System. DefenseScoop, quoting an Air Force press release, describes it as an "integrated system-of-systems designed to connect sensors, command and control and layered kinetic and non-kinetic capabilities." Air & Space Forces Magazine reported that Wilsbach said it would bring together kinetic and nonkinetic counter-drone capabilities, and that he offered no further details.

Wilsbach also announced a new point defense career field, which he said would be operational within two years. Air & Space Forces Magazine reported that the first two career field managers have already been selected. DefenseScoop quoted Lt. Gen. Jefferson O'Donnell, the Air Force deputy chief of staff for manpower, personnel and services, from the Air Force's release on the plans.

On acquisition, Air Force Secretary Troy Meink said on Sept. 14 that the service is exploring a new portfolio acquisition executive, or PAE, for what he called the "kit side" of point defense. He said it is "not going to be tomorrow" but is a question of when. According to Air & Space Forces Magazine, the Department of the Air Force currently has 26 PAEs, 17 for the Air Force and nine for the Space Force. A dedicated point-defense PAE would put counter-drone equipment in its own acquisition portfolio.

The War Zone described the announcements as the Air Force moving to take over defending its own bases against aerial attack. The service has developed new doctrine to do so. TWZ reported that the war against Iran exposed gaps in how the U.S. can defend its foreign installations, and its article showed video of a fatal Iranian missile attack on Muwaffaq Salti Air Base in Jordan in July. It also pointed to drone incursions at home and to the war between Russia and Ukraine. Air & Space Forces Magazine noted that the service has been racing to counter drones since unidentified drones hovered over Langley Air Force Base, Va., in late 2023.

Why It Matters

The September speeches set out a direction: a weapon system, a career field and possibly a PAE. Project Iron Sentry is an early example of a command acting on that direction for a specific theater. DefenseScoop's report ties the RFI to growing concern about North Korea's drone arsenal, including reported exercises in combined drone-and-missile attacks.

The RFI also shows a preference for systems that already exist. By asking for "combat-proven" systems through an accelerated-fielding program, 7 AF is pointing industry toward products that have been used in combat. It is not asking for new development.

Several things are still unknown. The RFI does not say how many systems 7 AF wants, how much money is available, or how Iron Sentry would fit into the Point Defense Weapon System Wilsbach described. Air Force leaders have not yet given details of that architecture. Meink also put no date on the point-defense PAE. Those answers will decide whether Iron Sentry becomes a quick regional purchase or the first piece of a service-wide program.

For now, APFIT-eligible vendors with fielded counter-UAS systems have until 8:00 a.m. KST on Oct. 13 to make their case.
