On 21 June 2025, President Trump announced the US had struck Iran’s Fordow Nuclear Facility with GBU-57A/B MOP bunker busting bombs. High-resolution imagery taken on 22 June 2025 shows the site after it had been struck.

Comparison of imagery before and after the strikes reveal changes to the terrain above the Fordow Nuclear Facility. Including subsidence, or the collapse of earth, along the ridgeline above the site and possible missile entry points on the side of the mountain.

The strike appears to have targeted parts of the facility that Iran had constructed into the mountain and then later covered. Historical imagery from 2009 shows these buildings under construction at these locations.

North Korea’s latest naval destroyer has been significantly damaged prior to its launch. In a rare acknowledgment, North Korea's state news agency KCNA reported yesterday an incident occurred with a new destroyer in Chongjin, which was close to being launched.

High resolution satellite imagery from @AirbusSpace shows the ship lies partially submerged on its side, tarpaulins draped over the wreckage in a visible attempt to contain the disaster.

The vessel, pictured days before, was almost ready. This was the second new destroyer built by the Pyongyang regime in the last year, with another launched in April in Nampo.

Today we are publishing a new investigation “Brothers in Arms” conducted in conjunction with @ReutersGraphics that details for the first time the significant scale of munitions transfers from North Korea to Russia since August 2023.

Link and findings below.

Since August 2023, four Russian-flagged vessels (Angara, Lady R, Maria, Maia-1) conducted at least 64 voyages between DPRK and Russian Far East ports.

Analysis indicates they delivered over 15,000 containers, estimated to hold 4.2-5.8 million artillery rounds and rockets.

Our estimates derive from analysis of hundreds of satellite images, detailed 3D models of vessels/containers, munition packing assessments and other sources.

Cloud cover and exclusion of cross-border rail mean these are conservative estimates.
