"Further Vulcan raids against the airport had been requested but not provided. The best use of the Victor tankers appeared to be the daily long range Nimrod surface surveillance sortie.
Concerns about radars led to the consideration of use of the American Shrike ainti-radiation missile. BLACK BUCK 4 on 27 May was called off after 5 hours because of problems with refuelling. On 31 May BLACK BUCK 5 took off with 4 Shrike missiles. A Sea Harrier attack was co-ordinated with the raid to keep the radars turned on. Two Shrikes were launched, and one exploded - the first had detonated about 45 foot from the TPS-43 antenna, inflicting significant damage - the second missed......
It was intended to use Shrike by the GR3s. The operational was delayed as RAF engineers assembled the system from parts air-dropped to
Hermes by a Hercules, but it was not ready when the Argentines surrendered.....
Another raid (BLACK BUCK 6) using Shrike on 3 June was hampered by the poor intelligence on the location of the radars...... The weather was also poor, so there could be no Harrier decoy sortie to get the radars turned on. Two missiles were successfully fired at a Skyguard site without much effect. Then, when trying to get home, the Vulcan had to divert to Rio de Janeiro because of a broken refuelling probe.......

On 10 June.... a report that four Pucaras had bombed and strafed 3 Para on the northern slopes of Mount Kent before returning to Stanley. No damage had been caused but Moore was worried that the airport was still in use and requested another BLACK BUCK raid on the morning of 12 June. The raid was mounted but was ineffective*. At 2120Z on 13 June, Woodward reported to CINCFLEET that: '
PR of Stanley airfield today shows that BLACK BUCK 7 bombs dropped on identical line to BLACK BUCK 2 without damage to the target'.

Early on 12 June, at 0850Z, there was the last Vulcan raid on Stanley airfield - BLACK BUCK 7. The intention was to attack the airfield parking and storage area with VT air-burst bombs, but impact fusing was set in error, and the 21 bombs fell wide of the target.
