US 'missile hunter' flies towards key nuclear silos after Iran rejects peace plan

A US Air Force RC-135S Cobra Ball aircraft was spotted on a mysterious mission toward America's nuclear silos on Wednesday.

The Cobra Ball, nicknamed 'missile hunter,' is a highly specialized intelligence aircraft designed to collect measurement and signature intelligence (MASINT) on ballistic missiles, using advanced optical and electronic sensors to track launches and re-entry phases.

The aircraft supports arms control treaty verification, missile defense analysis and threat assessment.

Flight tracking data showed the jet departing Offutt Air Force Base near Omaha, Nebraska, at 1.48 pm ET, before heading north through the Dakotas.

The jet is currently moving closer to Minot, North Dakota, home to Minot Air Force Base, which manages 150 Minuteman III intercontinental ballistic missiles (ICBMs) buried 70 feet underground. 

South Dakota, while no longer hosting operational missiles, once housed about 150 Minuteman II silos during the Cold War, which were decommissioned and dismantled by the early 1990s, though some underground control facilities remain.

The US currently maintains about 400 silo-based Minuteman III missiles across North Dakota, Montana, and Wyoming, forming the land-based leg of the nation’s nuclear deterrent.

Officials have not confirmed the reason for the flight, but the flight comes shortly after Iran rejected President Donald Trump's peace plan to end the conflict in the Middle East.

FlightRadar24 tracked the Cobra Ball leaving Offutt Air Force Base, where the craft is primarily housed under the control of the 55th Wing and 45th Reconnaissance Squadron.

The jet is currently traveling just miles east of Minot, outside of Devils Lake, about 35 to 60 miles from the outer missile field zones.

The US Air Force operates three Cobra Ball jets, which are equipped with a sophisticated array of optical and electronic sensors, recording media, and communications equipment.

The Cobra Ball routinely flies long-duration missions over the U.S. and overseas for training, sensor calibration, and support of missile tests.

Its crews undergo intensive, specialized training to operate the sophisticated sensors and accurately interpret missile data, making it a critical part of the nation’s strategic intelligence and nuclear deterrent infrastructure.

The craft can fit a minimum of two pilots, one navigator, three electronic warfare officers, two airborne systems engineers and two or more airborne mission specialists.

While the flight reflects routine training, calibration or missile-defense support operations, which the Air Force conducts regularly to maintain strategic readiness, it eerily coincided with the major development in the US-Iran war.

Trump's 15-point plan, modeled on his Gaza deal, would require Iran to dismantle all nuclear and long-range missile capabilities, open the Strait of Hormuz, and abandon proxy terror groups.

But Iranian state TV on Wednesday said that the regime had rejected the ceasefire proposal. Instead, Tehran is demanding the closure of all US bases in the Gulf, reparations, and an end to Israeli military strikes against Hezbollah in Lebanon.

Tehran is also seeking to bring the strait, a chokepoint for roughly a fifth of the world's oil, under its control, allowing it to charge transit fees on passing vessels, much like Egypt does with the Suez Canal.

A Trump official described Iran's demands as 'ridiculous' and 'unrealistic', warning that reaching a deal is now more difficult than before the war began as the President prepares a potential ground invasion force.

US and Iranian diplomats have not spoken through direct contact and instead communicate via Middle Eastern intermediaries from Egypt, Turkey, and Pakistan.

The President called for a one-month ceasefire on Tuesday, during which the two sides could thrash out the negotiations on the 15-point peace plan.

The plan now stands in complete contrast to the demands being issued from Tehran.
