At the time, the Boeing RC-135W Rivet t registration ZZ664, a jet specialized in data collection through signal interception (SIGINT), was intercepted by a pair of Russian Su-27 fighters. The minister reports that at a certain point during the follow-up, one of the Russian jets 'released' a missile close to the RC-135. Wallace used the word "released", which makes it difficult to know if the missile was ejected/fell (jettison) from the fighter, or accidentally fired.

It is also unknown what type of missile was launched. The Su-27 is normally armed with R-73 missiles, short range and heat guided, and R-27, medium range and guided by active, semi-active or heat radar depending on the variant.
The interaction between the British and Russian planes lasted 90 minutes, with the RC-135 safely returning to base, despite the Ministry having defined the event as a “potentially dangerous engagement”.

Wallace stated that he communicated the incident to his Russian counterpart, Sergei Shoigu.“In my letter, I made it clear that the aircraft was unarmed, in international airspace and following a pre-notified flight path. I thought it prudent to suspend these patrols until a response has been received by the Russian State.”.
An investigation by Moscow pointed out that a technical failure in the fighter caused the launch of the weapon. Wallace also emphasized that the action did not appear to be a "deliberate escalation".

The incident caused the RAF to impose a brief pause on reconnaissance flights over the Black Sea. The missions have returned, but now the RC-135s fly escorted by Typhoon FGR.4 fighters. Interestingly, the same plane would have violated Russian airspace on another occasion, In August.
The RC-135W is an aircraft dedicated to surveillance and electronic data collection missions, equipped with a series of antennas across the fuselage to capture multiple signals. The RAF operates its three RC-135Ws in 51 and 54 Squadron, both based at Waddington Air Force Base.
