The second attempt took place on October 15, at the onset of Operation Stouthearted Men, the Israeli military operation to cross the Suez Canal.  Despite significant setbacks caused by poor sea conditions, the second attack was on the verge of success when the Israeli Air Force once again intervened, and this, coupled with Israeli reinforcements, repelled the Egyptian attack.

Since 2003 the base has gradually received more squadrons of F-16s.  A third runway was built in the mid-2000s decade as part of a project to accommodate the transfer of military activities previously taking place at Ben Gurion Airport (Air Force Base 27) to Nevatim.
