Those destined for the F/A-18F Super Hornet (USN Only) or the F/A-18D Hornet (USMC only) will become WSOs. Intermediate picks up where Primary ends for USAF SWSOs. After the instrument phase of training, students move to visual navigation (VNAV) "low levels" at 2000'AGL, and finish in the T-6 with a final training block called "forms" (formation flying). Forms consist of four flights of learning the basics of close in formation flying. After forms, SWSOs head back to ground school to learn an entirely new aircraft, the USN T-39 Sabreliner. The T-39 is used as an intermediate instrument and low-level trainer for SWSOs, where they receive a total of eight flights. Students are required to learn the aircraft in a two-week ground school period before they go flight side. In contrast, T-6 ground school is four weeks. Training ends at either VT-10 or VT-4 with the "i-grad" ceremony and top graduate award. VT-86 is where all the training comes together to culminate in the SWSO receiving his or her wings of gold. In the T-39, a USN twin-engine jet trainer, SWSOs learn advanced instrument flying, radar navigation (consisting of navigating using an A/G radar from early F-16s), and composite visual/radar navigation. Training takes place on both VR and IR routes that criss-cross the south east United States. After A/G training, track selection takes place. Navy SWSOs select either the F/A-18F Super Hornet, or the E/A-18 Growler. Marine SWSOs by default select the F/A-18D Hornet. The final three months of some of the hardest training at Pensacola will leave the SWSO F/A-18 selectee with their wings of gold. Air Force WSOs no longer train at VT-86. Following the winging ceremony, USN and USMC WSOs will proceed to a Fleet Replacement Squadron (FRS) and USAF WSOs to a Formal Training Unit (FTU) to complete advanced ground school and flight training to prepare them for their "operational" combat aircraft in the deployable operating forces.
