Marshall Aerospace Details Critical C-130 Hercules Paint Stripping Process
Marshall Aerospace performs chemical paint stripping on C-130 Hercules aircraft to expose bare metal for essential maintenance inspections.
This article is based on an official press release from Marshall Aerospace.
The Silver Skin: Inside the Critical C-130 Paint Stripping Process
For military aviation enthusiasts and industry observers, the C-130 Hercules is most recognizable in its operational livery, typically grey, camouflage, or specific squadron markings. However, before these workhorses undergo major maintenance, they must be stripped down to their raw, metallic core. According to Marshall Aerospace, this transformation is not merely aesthetic but a critical safety requirement for ensuring the airworthiness of global fleets.
In a recent release titled “What lies beneath,” Marshall Aerospace detailed the rigorous process of chemically stripping C-130 Military-Aircraft to bare metal. This procedure, often hidden behind closed hangar doors due to safety protocols, is the first step in a “deep tissue” examination of the airframe. By removing layers of paint and primer, maintenance crews can expose the aircraft’s “silver skin,” revealing microscopic defects that would otherwise remain invisible to the naked eye.
As a “Gold Standard” partner for Lockheed Martin, Marshall Aerospace performs this essential work at its facility in Cambridge, UK. The company notes that this capability is vital for Planned Maintenance Intervals (PMI), a heavy maintenance check that occurs roughly every five to six years. Without this complete strip, engineers cannot guarantee the structural integrity required for the demanding operational profiles of clients like the US Marine Corps.
The Transformation: From Paint to Bare Metal
The process of stripping a C-130 is an intense industrial undertaking that typically occurs within the first 10 days of the aircraft’s arrival for maintenance. Marshall Aerospace describes the procedure as a complete “transformation” that takes place in a dedicated “paint barn” large enough to house a Boeing 747.
Chemical Stripping and Containment
Unlike minor inspections where paint remains intact, major maintenance events require the removal of all coatings. Marshall Aerospace utilizes a specialized chemical stripping process to achieve this. Before the chemicals are applied, technicians meticulously mask sensitive areas of the aircraft. Windows, composite parts, and radomes are covered with aluminum tape and protective materials to prevent chemical intrusion, which could damage these delicate components.
Once prepared, the aircraft is treated with a chemical agent designed to loosen the bond between the paint, primer, and the metal skin. The coating is then washed away, leaving the aluminum alloy structure exposed. Because the process involves harsh chemicals and heavy metals from the old paint, Marshall emphasizes the use of advanced environmental abatement systems. These systems capture hazardous waste and filter the air, ensuring that pollutants do not escape into the atmosphere or local water supply.
Safety Protocols
The environment inside the paint barn is strictly controlled. Technicians working on the strip must wear full Personal Protective Equipment (PPE), including respirators and protective suits. This level of protection is necessary to handle the stripping agents safely while preparing the aircraft for the next stage of its maintenance journey.
Why the Strip is Non-Negotiable
While a freshly painted aircraft looks impressive, Marshall Aerospace asserts that the true value of maintenance lies in what is uncovered when the paint is removed. The “silver” state of the aircraft allows for a level of inspection that is impossible to achieve on a painted airframe.
Detecting Hidden Defects
Paint can effectively hide stress cracks, corrosion, loose rivets, and fatigue issues. By stripping the aircraft to bare metal, engineers can perform rigorous Non-Destructive Testing (NDT) and visual inspections on every inch of the skin. This “detective work” is crucial for identifying structural weaknesses that could compromise the aircraft’s safety during flight.
“We understand that there is more to aircraft paint than the appearance… looking at what is under the surface is key to our maintenance inspections.”

Weight and Balance
Beyond inspection, the stripping process plays a role in aircraft performance. Over time, multiple layers of paint can add significant weight to an airframe. Stripping and repainting help maintain the aircraft’s correct weight and center of gravity, ensuring it performs within its design specifications.
AirPro News Analysis
The emphasis on deep-level maintenance capabilities like paint stripping highlights a broader trend in the aerospace defense sector: the extension of airframe life. With the C-130 platform remaining a backbone of global military logistics, the ability to detect and repair fatigue in aging airframes is becoming as valuable as the production of new units. Marshall Aerospace’s expansion into the United States, with a new facility in Greensboro, North Carolina, suggests a growing demand for these heavy MRO capabilities on both sides of the Atlantic.
Marshall’s Legacy and Future
Marshall Aerospace has established itself as a global authority on the C-130 platform. The company has been working on the Hercules since 1966 and became the first authorized C-130 Hercules Service Centre (HSC) in the world in 1974. In February 2025, the company celebrated 50 years holding this designation.
The company services major international fleets, including the US Marine Corps and the Royal Air Force. With the upcoming facility in Greensboro, Marshall is set to expand its “paint barn” capabilities, bringing its specialized stripping and maintenance processes closer to its North-American customer base.

USAF Launches EPAWSS Speedline to Accelerate F-15E Modernization
The USAF establishes an EPAWSS Speedline at Warner Robins to rapidly upgrade F-15E Strike Eagles with advanced electronic warfare systems starting June 2026.
This article is based on an official press release from the Air Force Life Cycle Management Center.
Air Force Launches EPAWSS Speedline to Accelerate F-15E Modernization
On May 26, 2026, the Air Force Life Cycle Management Center (AFLCMC) announced the establishment of a dedicated “Speedline” facility at the Warner Robins Air Logistics Complex (WR-ALC) in Georgia. This new initiative is designed to rapidly accelerate the installation of the Eagle Passive Active Warning Survivability System (EPAWSS) on the U.S. Air Force’s F-15E Strike Eagle fleet.
According to the official press release, the Speedline facility is slated to receive its first F-15E aircraft for installation in June 2026. By decoupling these critical electronic warfare upgrades from standard Programmed Depot Maintenance (PDM) schedules, the Air Force aims to field advanced defensive capabilities much faster than previously possible.
We note that this shift in maintenance strategy allows the military to upgrade jets up to five to seven years ahead of their routine maintenance cycles. This collaborative effort between the AFLCMC’s F-15 System Program Office and the WR-ALC is expected to significantly boost fleet readiness against modern electromagnetic threats.
Breaking the Maintenance Bottleneck
Operational Independence
Historically, major system upgrades for fighter aircraft have been tied to their routine depot maintenance schedules, which can create bottlenecks for fielding urgent technology. The AFLCMC’s new Speedline operates entirely independently of the standard PDM line.
This operational independence provides the F-15 System Program Office and WR-ALC the flexibility to install the EPAWSS on aircraft that are not due for routine maintenance for another five to seven years. By treating the electronic warfare upgrade as a standalone priority, the Air Force can modernize its fleet at a pace dictated by tactical necessity rather than logistical routine.
Understanding the EPAWSS Upgrade
Replacing Cold War-Era Technology
The Eagle Passive Active Warning Survivability System is a next-generation, all-digital electronic warfare suite. Based on the provided research data, it is designed to replace the legacy Tactical Electronic Warfare System (TEWS), which relies on Cold War-era analog equipment.
Developed by prime contractor BAE Systems, with Boeing serving as the prime contractor for integration, EPAWSS provides fully integrated radar warning, geolocation, situational awareness, and self-protection solutions. The system allows the aircraft to detect, identify, and defeat surface and airborne threats in highly contested, dense signal environments.
Financial and Production Milestones
The U.S. Air Force officially cleared EPAWSS for full-rate production in early 2025. Concurrently, the Air Force awarded a $615.8 million contract to Boeing to cover the installation of these systems. Shortly after this award, the first fully equipped F-15E was delivered to the 48th Fighter Wing at RAF Lakenheath in the United Kingdom, marking a major milestone in the modernization of the 4th-generation fleet.
Strategic Importance and Lethality
Expanding the F-15E’s Capabilities
The integration of EPAWSS is not merely a defensive measure; it is a comprehensive upgrade to the aircraft’s survivability and lethality. In the official AFLCMC release, military leadership emphasized the strategic necessity of the system.
“The F-15E Strike Eagle remains a cornerstone of our tactical airpower and deep strike capabilities. The integration of advanced electronic warfare suites, such as the Eagle Passive Active Warning Survivability System, ensures the F-15E will not just survive, but actively disrupt and dismantle adversary kill chains in the most highly contested, electromagnetically dense environments.”
, Lt. Col. Matthew Heil, F-15 Program Office, EPAWSS Materiel Leader
AirPro News analysis
We observe that the creation of the EPAWSS Speedline reflects a broader Department of Defense trend toward agile logistics and sustainment. By separating critical combat upgrades from time-consuming depot maintenance, the military is demonstrating a commitment to fielding new technologies to the warfighter at a much faster pace.
Furthermore, as the U.S. Air Force continues to develop and field 5th-generation fighters like the F-35 and F-22, alongside future 6th-generation platforms, maintaining the survivability of 4th-generation “workhorse” aircraft is a strategic priority. EPAWSS ensures that older airframes like the F-15E can safely and effectively operate alongside stealth fighters in modern, highly contested combat scenarios, bridging the gap between legacy platforms and future air dominance initiatives.
