Executive Summary
Diplomatic engagement between the United States and Iran continued to shape regional dynamics, with Tehran signaling conditional flexibility on its nuclear program via Oman while Washington reinforced maritime security measures in the Strait of Hormuz. At the same time, U.S. military posture in the Middle East remained active but more measured, marked by the redeployment of fighter aircraft to Jordan and a slowdown in air defense cargo flows. Broader global tensions persisted as NATO prepared to expand its presence in the Arctic, Russia highlighted both military production capacity and force concentration in the Far East, and renewed debate emerged over nuclear deterrence following accusations of underground testing involving China. Alongside these developments, alliance commitments were reaffirmed amid concerns over the erosion of the postwar international order, while defense industry activity reflected sustained investment in advanced missile systems, artificial intelligence, hypersonic technologies, and international industrial partnerships.
This daily brief examines heightened military posturing and strategic deployments amid ongoing diplomatic engagement, as major powers balance deterrence, signaling, and negotiation. It assesses force movements, operational readiness, and alliance dynamics alongside parallel diplomatic tracks, highlighting indicators that shape escalation risk and crisis management across multiple theaters. The brief is designed to support timely situational awareness by contextualizing tactical developments within broader geopolitical and security trends.
U.S. POSSIBLE ATTACK ON IRAN - MIDDLE EAST DEPLOYMENT
Six F-35A Lightning II fighter jets that recently flew from the United States to the United Kingdom are now departing RAF Lakenheath to deploy to Muwaffaq Salti Air Base in Jordan. The F-35s are being supported by four KC-135R aerial refueling tankers. The six F-35s departing RAF Lakenheath are expected to join another six F-35A aircraft currently stationed in Spain, replacing twelve F-15E Strike Eagles that are leaving Jordan and returning to the United States.
Six F-35A fighter jets previously stationed at NAS Rota in Spain flew to Morón Air Base after the base resumed operations following a runway incident involving a KC-46A tanker aircraft. The F-35s are expected to be deployed to Jordan in the coming days.
Cargo flights transporting air defense systems and related equipment to bases in the Middle East are continuing, although the overall frequency of flights has decreased. Since January, the recorded air defense and equipment transfer flights are as follows:

• Prince Sultan Air Base: 19
• Ali Al Salem Air Base: 13
• Al Udeid Air Base: 13
• Diego Garcia NSF: 9

GLOBAL SECURITY DEVELOPMENTS
Iran is continuing negotiations with the U.S. over its nuclear program via Oman, alongside regional actors including Syria and Lebanon.
