Top Air Force Revives Iconic Bomber Aircraft with $23.7 Million Upgrade

WASHINGTON- The US Air Force (USAF) is set to reinstate the B-2 Spirit of Georgia into service on November 6, 2025, after a substantial repair costing $23.7 million. This restoration process spans slightly under four years.

The aircraft encountered a mishap on September 14, 2021, at Whiteman Air Force Base (SZL), where its left main landing gear collapsed, leading to significant damage to its stealth features.

With this repair, the B-2 fleet’s count climbs back to 19 operational bombers out of an original 20, as two previous aircraft were lost in accidents deemed economically unfeasible to repair. Each bomber plays a crucial role in maintaining readiness.

US Air Force Restores B-2 Spirit

The incident began on September 14, 2021, when the Spirit of Georgia faced a malfunction during takeoff at Whiteman Air Force Base (SZL). A vital mechanical lock failure caused the left main gear to buckle, damaging the wing and stealth coatings.

Recovery teams quickly responded, utilizing inflatable airbags to stabilize the aircraft and secure the damaged gear. Once towed to a hangar, evaluations could commence.

Col. Jason Shirley from the B-2 System Program Office noted that the rapid action taken by maintenance and engineering personnel was crucial. Damage was concentrated in the left main landing gear bay and the lower wing area.

This incident grounded the B-2 fleet for 18 months, with initial assessments considering the bomber a potential total loss.

A similar incident in 2022 with another B-2 bomber, the Spirit of Hawaii, resulted in a complete loss due to fire damage, emphasizing the importance of each unit.

Structural Assessment and Ferry to Palmdale

Through meticulous laser inspections, engineers verified that critical fittings within the landing gear bay adhered to safety tolerances. Structural load analysis further validated the integrity of primary components.

Following a year post-crash, temporary fixes allowed the Spirit of Georgia to transport to Northrop Grumman’s Plant 42 (PMD) in Palmdale, California, arriving on September 22, 2022. These measures saved the government approximately $52 million and expedited the repair timeline.

At Plant 42, the bomber underwent Programmed Depot Maintenance, focusing on tailored repairs with a structured four-phase approach. Phase 1 centered on designing the repairs and sourcing necessary materials, while Phase 2 involved constructing test panels for validation.

Advanced Composite Repairs

Phase 3 commenced with structural repairs, utilizing a composite skin section from another aircraft, which led to cost savings and a quicker turnaround. The left wingtip and crucial components were addressed during this phase, ensuring functionality to handle aerodynamic loads and fuel pressures.

As repairs continued on May 12, 2025, engineers had to navigate challenges related to the curing process in confined areas, employing custom solutions to manage precise temperature controls.

Maintaining cleanliness was vital during the repair of composite fuel tanks, ensuring contamination levels were minimized. This comprehensive restoration effort, totaling $23.7 million, stands in stark contrast to the exorbitant costs of previous accidents.

Future Sustainment

This project marks the first use of a new composite resin, demonstrating its reliability and effectiveness in large-scale repairs. Engineers employed innovative scarf repair techniques to maintain optimal stealth capabilities.

These advancements are expected to enhance future operations, resulting in reduced downtime and extended aircraft lifespan. Cindy Connor, the Air Vehicle and Systems Management Branch deputy chief, recognized the essential support from Air Force Global Strike Command throughout this process.
