Iran’s Asymmetric Counterair Campaign: Attacking the U.S. Air Force’s Nests and Eggs
War on the Rocks – On March 27, Iranian drones and missiles struck Prince Sultan Air Base in Saudi Arabia, destroying an E-3 Sentry, an airborne command center for U.S. operations in the region, and damaging multiple KC-135 tankers. It was not the first strike. Earlier in the month, an Iranian attack had already damaged five KC-135s at the same base. In the history of these aircraft, no enemy had ever achieved such a hit until Iran did both — within two weeks.
Russia’s massive Black Sea problem is worse than it looks
Naval News – On paper, the Russian Navy remains the dominant force in the Black Sea. But after ceding control to Ukraine’s uncrewed surface drones, it now faces a mounting crisis: its key base at Novorossiysk is increasingly untenable, unless Moscow is willing to absorb further warship losses.

Pinning the tail on the Moskva: POPPY and the dawn of satellite ocean surveillance
The Space Review – In 1963, American reconnaissance satellites overflew a shipyard in Mykolayev, Ukraine, on the Black Sea, and photographed evidence of a new large vessel under construction. But it was not until 1965 that satellite photographs revealed it to be “an unusual ship,” in the words of a CIA report. Later that year, it became clear that it “was a helicopter platform, with either an ASW or amphibious assault mission.” It was launched in 1967 and began sea trial inside Soviet waters. This was a time when the Soviet Union was beginning to send its fleet further out to sea, challenging the US Navy, and any new large warship was of great interest to the Navy admirals.
Pentagon Adds to Pacific Refueling Capacity With New Philippine Depot

Iran’s Anti-Access and Area Denial Strategy Is Cruder Than China’s But Still Dangerous
War on the Rocks – Iran has consciously adapted the operational logic of the Chinese anti-access and area denial strategy to its own resource constraints. It has extended that logic through proxy forces across two of the world’s most critical maritime chokepoints — the Strait of Hormuz and the Bab el-Mandeb — and constructed a denial architecture that is incomplete by Chinese standards but sufficient for Iran’s strategic purposes. This architecture now operates across three layers: denial of the forward basing infrastructure from which U.S. power projection begins, denial of access through two interlocking maritime chokepoints, and area denial within the Persian Gulf itself. Each layer is imperfect. Together, they compound to a sufficient deterrent.
The Royal Navy’s reputation takes a battering
Navy Lookout – Among other scattergun criticisms of the UK, President Donald Trump has said: “You don’t even have a navy. You’re too old and had aircraft carriers that didn’t work.” Here, we consider how his remarks contain elements of truth, but the wider picture is more nuanced.

Closing the Air and Missile Defense Gap in the Indo-Pacific
War on the Rocks – Sensing vulnerability, the United States and its regional allies and partners are ramping up procurement of air and missile defense assets, though progress is likely to be constrained by competing spending priorities and already overstretched defense industrial bases. These constraints underscore the need for complementary approaches that can deliver near-term gains without relying solely on expanded procurement. Networking missile sensors and interceptors across the United States and its Indo-Pacific allies and partners is one such approach. Coalition air and missile defense can generate operational efficiencies in sensing and interception that have the potential to shrink Chinese air and missile advantages. While compelling in theory, is it feasible in practice? Can the United States and its allies and partners navigate the challenging geography and politics of the Indo-Pacific to counter Chinese air and missile advantages through coordinated air and missile defense?
