Training begins with several weeks of ground school followed by remnants of the "super-fo" program from the U.S. Navy where the SNFO takes front seat of the new T-6 Texan II for six "contact" flights where the student will become familiar with the T-6. The SNFO is treated like a pilot training student for these six flights. After Contacts, the SNFO goes back to academics to learn instrument flying rules. Primary ends with a final instrument checkride. After primary the SNFO is compared to his or her shipmates and selected for either land-based naval aircraft or tailhook aircraft. Those SNFOs destined for the carrier-based E-2C or E-2D Hawkeye will be known as air control officers and combat information center officers, while those destined for the EA-18G Growler (USN only) will be electronic warfare officers (EWO). Those destined for the F/A-18F Super Hornet (USN Only) or the F/A-18D Hornet (USMC only) will become WSOs.
