of Tyndall´s 55 F-22 stealth fighters were flown to Wright-Patterson Air Force Base near Dayton, Ohio before the storm. Many of the seventeen F-22s which were left behind became damaged. The extent of the damage to the planes was then known. According to US Senator Bill Nelson and Congressman Matt Gaetz, the aircraft left behind were not in a condition to be flown. A spokesperson for the Air Force said that none of the F-22s were destroyed and that they "believe at this time that they are all repairable." In April 2019, the Air Force estimated the hurricane damage to the base at $4.7 billion. In April 2022, Detachment 1 of the 823rd Red Horse Squadron inactivated at Tyndall and was replaced by the 801st Red Horse Training Squadron. The unit's role is to provide integrated, realistic training and exercises to combat support teams. Environmental issues The soil of an aerial gunnery school training range on Tyndall was contaminated with lead from 12-gauge shotgun shells during World War II. Tyndall Elementary was constructed on the former site of this training range; In 2009 a $5.5 million remediation of the soil at the school was completed and a perimeter fence put up, including a "buffer zone" outside the fence. When the hurricane destroyed the fence in October 2018, contractors erected a temporary replacement slightly offset which included some sections contaminated with lead to be located within the campus. As of August 2019, a new perimeter fence was planned to be erected until 12 August 2019 and School district officials were planning to contact families of the 180 affected students.
