In May 1947, flight leader Lt. Cmdr. Bob Clarke replaced Butch Voris as the leader of the team. The team with an additional fifth pilot, relocated to Naval Air Station (NAS) Corpus Christi, Texas. On 7 June at Birmingham, Alabama, four F8F-1 Bearcats (numbered 1–4) flew in diamond formation for the first time which is now considered the Blue Angels' trademark. A fifth Bearcat was also added that year. A SNJ was used as a Japanese Zero for dogfights with the Bearcats in air shows.
