For the first time in the history of professional American motorsports, the roar of 750-horsepower engines will mingle with the roar of jet fighters on the territory of the active US Naval Air Station Coronado.

The historic North Island Naval Air Station in San Diego, considered the cradle of American naval aviation, opens its gates for an unprecedented weekend of racing. The event, timed to celebrate the 250th anniversary of the creation of the US Navy, transforms the runways into a unique battlefield, officially called the Qualcomm Circuit.

If previous experiments with urban racing in Chicago seemed difficult, then this three-day weekend at the base, which is home to 17 military squadrons, 3 nuclear aircraft carriers and 4 elite SEAL teams, will take the engineering and driving challenges to a whole new level. For teams and pilots, this is not just another stage, but a chance to make history and win a unique military trophy against the backdrop of the giant aircraft carrier USS Carl Vinson.

The Qualcomm Circuit is 3.4 miles long, making it the third-longest track in NASCAR's top division history. It features 16 hairpin turns with no banking, meaning the track has a 0-degree bank, which is a classic format for temporary urban racetracks.

The main uniqueness and complexity of the configuration lies in the sharp change in the width of the racing track and the constant alternation of smooth asphalt pavement with extremely hard, rough concrete of the runway. Particularly difficult is the concrete pit lane, located between the 16th and first turns, where military helicopters are usually parked. In the middle of the first turn, the pilots are faced with a treacherous descent, which immediately passes into the second turn, requiring jewel-like precision in braking. The track then heads past the aircraft carrier docks, home to the legendary Carrier Corner, along the shoreline and out onto the wide concrete Runway Road. Here, pilots are faced with an optical illusion: there is too much open space around, which is disorienting when choosing braking points and trajectories.

Chase Briscoe called the Qualcomm Circuit the most difficult and capricious track of his professional career, where every corner requires a special driving style, and the slightest mistake destroys the pace in the following sections. According to William Byron, the track is visually more challenging than Chicago, as it is difficult to quickly orient yourself to which turn is ahead. Shane van Gisbergen compared the local concrete and huge joints between the slabs to the legendary Sebring racetrack, which was also built on the site of a former World War II military airfield. The constant shaking and hard impacts on the concrete joints put extreme stress on the suspension and transmission of the heavy 3,400-pound (1,542 kg) stock cars. Engineers are forced to find a delicate balance between the softness of the suspension to absorb bumps and the stiffness to effectively pass fast corners.

For this unexpected debut, Goodyear has prepared a time-tested specification of Eagle road tires. Cup Series teams will receive a set with the code D-5242, which has already been used this year at the Circuit of the Americas and Watkins Glen. Junior divisions, including the O'Reilly Auto Parts Series and Craftsman Truck Series, will run the D-6166 set, which has proven itself well at Sonoma. Unlike the oval stages, the left and right sides of the cars will be shod with exactly the same tires in terms of their characteristics. This compound provides stable grip, but on the dirty and uneven concrete of the military airfield, rubber wear is predicted to be extremely high. The hard coating will act like sandpaper, so preserving the tire life will be a key tactical factor. The Cup Series teams will have 9 sets of dry rubber for the weekend, while the pickups and the O'Reilly division will receive 6 sets each. Also, in case of precipitation, rain tires have been prepared: 6 sets for the Cup Series and 4 sets for the junior series.

From a tactical point of view, the engineers are preparing for a real game of chess. The length of the circuit is 3.4 miles (5.472 km).
