A high-ranking United States military official told congressional lawmakers on Tuesday that the Department of Defense has established an aggressive target to have eighty percent of its global F-35 Lightning II stealth fighter jet fleet fully ready for combat missions by the year 2030. However, the senior officer paired this ambitious objective with a stark, detailed warning that the military's internal maintenance infrastructure and international logistics pipelines have utterly failed to keep pace with the advanced stealth fighter platform's rapid operational expansion.
Lieutenant General Gregory Masiello delivered the comprehensive assessment while testifying before the Senate Armed Services Committee on Capitol Hill. During his formal remarks, Masiello described the fifth-generation stealth fighter as the absolute cornerstone of contemporary United States and allied military power, emphasizing its unparalleled role in modern global deterrence. To illustrate the immense scale of the program, the general revealed that the sophisticated aircraft is currently deployed across forty-two separate military bases distributed worldwide. Furthermore, the platform has been successfully integrated onto twenty-three aircraft carriers and amphibious assault ships globally, a total that includes ten vessels operated by the United States Navy and thirteen operated by international allied nations.
General Masiello emphasized that the F-35 has transitioned out of its developmental phase and has been heavily utilized in numerous high-stakes real-world military operations in recent years. Most notably, he confirmed that the stealth fighter played a decisive tactical role in conducting precision air strikes on heavily fortified targets inside Iran during the major conflict that was launched on February 28 by the United States and Israel. Highlighting the aircraft's advanced radar-evading capabilities and sensor fusion suites, the general defended the program's strategic value during intense combat. He noted that this specific aircraft is the only asset in the global inventory that can successfully strike highly defended targets that cannot otherwise be reached by conventional means, possessing the advanced sensory capacity to see everything across the modern electronic battlefield.
While defending the combat effectiveness of the airframe, Masiello identified improving fleet-wide readiness as his absolute highest priority moving forward. He cited a massive, structurally dangerous mismatch between the physical size of the expanding global F-35 fleet and the underlying industrial logistics system tasked with supporting it. The general laid out a clear mandate for his current leadership role, stating that his primary job is to deliver a reliable, cost-effective, and affordable system capable of sustaining an exceptionally high operational tempo, while charting a definitive, measurable path to achieving eighty percent mission-capable rates no later than 2030.
The core of the current readiness crisis, according to Masiello's detailed testimony, stems from a severe lack of long-term infrastructural planning during the earlier phases of the program. He explained to the Senate committee that the military's current global sustainment, repair, and supply system was originally engineered and scaled decades ago to support a maximum operational fleet of approximately seven hundred to eight hundred total aircraft. However, the rapid pace of international production has dramatically outstripped that original baseline. To date, international governments have formally accepted delivery of over one thousand three hundred F-35 aircraft worldwide, leaving the legacy maintenance network completely overwhelmed and underfunded. The general pointed directly to this stark mathematical disparity as the primary root cause behind the military's ongoing readiness challenges.
In addition to addressing domestic shortfalls, Masiello highlighted the rapidly growing allied and international dimension of the Joint Strike Fighter program. He pointed out that international partner nations now own, maintain, and operate the vast majority of the F-35s deployed across key global theaters of operation, shifting the burden of regional defense away from unilateral American deployments. To contextualize this shift, the general provided a forward-looking projection of the security landscape in the European theater. He noted that within just a few years, almost eight hundred F-35 stealth fighters will be permanently distributed across multiple sovereign European nations. Incredibly, less than ten percent of that massive collective regional force will consist of United States military aircraft, demonstrating the degree to which American allies are integrating the platform into their core national defense architectures.
The general's urgent remarks to the Senate Armed Services Committee arrive in the immediate wake of a highly critical, independent investigation published by the Government Accountability Office. The federal watchdog agency's recent report exposed severe systemic vulnerabilities within the F-35 program, revealing that only about twenty-five percent of the United States F-35 fleet was classified as fully mission capable last year. Furthermore, the Government Accountability Office discovered that the fleet's overall, baseline mission-capable rate—which measures an aircraft's ability to perform at least one of its assigned mission sets—had deteriorated to a disappointing forty-four percent. The independent report cited exponentially rising sustainment costs, persistent and widespread shortages of vital spare parts, and a chronic reliance on private contractors for basic depot-level maintenance as the primary drivers behind the fleet's declining operational health.
As the Senate committee concludes its review of the defense budget, Masiello's testimony underscores the immense challenge facing the Pentagon as it attempts to overhaul its industrial base, streamline supply chains, and build out the robust maintenance infrastructure required to transform its premier stealth fighter into a reliably ready combat asset before the end of the decade.
