If you served at NAS Miramar — or worked there as a civilian contractor — and you’ve just been diagnosed with mesothelioma, asbestosis, or lung cancer, the clock is already running. VA benefits carry no filing deadline, but federal civil claims do. NAS Miramar reportedly contained asbestos-containing materials (ACMs) throughout its hangars, boiler plants, steam systems, barracks, and maintenance facilities. Thousands of sailors, Marines, and civilian workers allegedly inhaled asbestos fibers during service or employment there. These diseases carry latency periods of 20 to 50 years — which is exactly why diagnoses are landing now, decades after men and women left Miramar.

Location and Command History

Naval Air Station Miramar sits in the Miramar community of San Diego, California, approximately 12 miles north of downtown. The installation began as Camp Kearny during World War I, was reactivated by the Navy in 1943 as Marine Corps Air Depot Miramar, and passed through several command designations before becoming NAS Miramar in 1952.

From 1969 through 1996, NAS Miramar hosted the Naval Fighter Weapons School — known worldwide as “Top Gun” — making it one of the most operationally active air stations on the West Coast. Following the 1993 Base Realignment and Closure process, the Marine Corps assumed control in 1997 and redesignated the installation Marine Corps Air Station Miramar.

Operational Periods and Infrastructure Development

The installation supported Navy and Marine Corps aviation personnel through:

  • World War II and post-war era (1943–1952) — Initial construction and base infrastructure established
  • Korean War expansion (1950–1953) — Rapid build-out of permanent facilities
  • Cold War operations (1950s–1980s) — Sustained high operational tempo with continuous facility maintenance
  • Vietnam War era (1964–1973) — Intensive operations and facility upgrades
  • Post-Cold War operations (1980s–1990s) — Infrastructure modernization projects

Asbestos in Military Construction

Federal Construction Standards and Military Procurement

The U.S. military built and maintained facilities using ACMs at a scale rarely matched in the private sector. Federal construction specifications and military procurement standards from the 1930s through the early 1970s called for ACMs across virtually every category of permanent construction.

Products from Johns-Manville, Owens Corning, Armstrong World Industries, Celotex, and Georgia-Pacific were reportedly specified in federal military construction contracts. Military engineers also allegedly specified Kaylo pipe insulation, Thermobestos boiler block insulation, Aircell spray-on fireproofing, and Gold Bond gypsum board products throughout naval installations.

Military architects selected asbestos-containing products for four practical reasons:

  • Thermal insulation — Superior heat retention in boiler systems, steam lines, and pipe work
  • Fire resistance — Required in hangars, munitions storage, and flight operations facilities
  • Durability — Longevity in the high-moisture and high-temperature environments common to naval installations
  • Cost — Less expensive than alternative materials meeting the same performance specifications

Naval air stations faced particular exposure risk because of their boiler plants, steam distribution systems, aircraft hangars, and heavy maintenance shops. EPA regulatory action in the mid-1970s began reducing asbestos use in new federal construction, but legacy materials installed in earlier decades remained in place for years — sometimes decades — afterward.

  • Pipe insulation in individual units and common utility areas, materials marketed as Kaylo and Thermobestos
  • Roofing materials containing asbestos documented in military family housing of that era, products from Georgia-Pacific, Celotex, and Pabco

Who Was Exposed to Asbestos at NAS Miramar

Exposure at NAS Miramar was not limited to any single occupational category. Those reportedly at highest risk included:

Military Service Members

  • Naval aviators and flight crew — Assigned to hangar-based squadrons, working in and around aircraft maintenance areas where disturbed Johns-Manville Kaylo insulation, Monokote fireproofing, and asbestos-containing transite panels allegedly generated airborne fibers
  • Aviation maintenance technicians and plane captains — Working daily in hangars and maintenance bays, in close proximity to Eagle-Picher and Crane Co. insulated pipes and Aircell structural fireproofing
  • Marine Corps personnel — Assigned following the 1997 transition, encountering deteriorating legacy ACMs during ongoing operations and facility renovations
  • Enlisted trades personnel — Assigned as pipefitters, plumbers, boilermakers, electricians, and HVAC technicians with direct responsibility for mechanical systems containing Johns-Manville, Garlock Sealing Technologies, and Combustion Engineering products

Civilian Employees and Contractors

  • Civilian pipefitters, plumbers, and boilermakers — Working on steam systems as government civilian employees or contract workers, disturbing Thermobestos, Kaylo, and Garlock gasket materials
  • Electricians and HVAC technicians — Disturbing insulation and fireproofing materials from Owens Corning, Armstrong World Industries, and W.R. Grace during installation and maintenance
  • Insulation workers — Applying and removing Johns-Manville, Eagle-Picher, and Owens-Illinois pipe insulation during routine and emergency maintenance, including members of Heat and Frost Insulators unions
  • Construction and renovation contractors — Performing demolition, remodeling, and systems upgrades with exposure to Celotex, Armstrong World Industries, and Georgia-Pacific materials, particularly during infrastructure modernization in the 1980s and 1990s

Peak Exposure Periods and High-Risk Activities

Construction and Initial Installation

Exposure was allegedly most concentrated during several distinct periods:

  • World War II-era construction through the late 1940s — Established foundational infrastructure using Johns-Manville, Owens Corning, and Celotex ACMs standard in federal construction at the time
  • Korean War expansion (early 1950s) — Added permanent construction incorporating Armstrong World Industries, Eagle-Picher, and Crane Co. materials

Operational and Maintenance Periods

  • Vietnam War-era operational tempo (1964–1973) — Increased maintenance activity in hangars and shops where Johns-Manville Kaylo, Thermobestos, and Monokote materials were present
  • Cold War operations (1950s–1980s) — Continuous maintenance and repair in ACM-containing environments involving Garlock Sealing Technologies products, W.R. Grace spray-applied fireproofing, and Owens-Illinois pipe insulation

Renovation and Demolition

Renovation and demolition work continuing into the 1980s and 1990s generated some of the highest documented fiber concentrations, as previously intact Johns-Manville Unibestos, Monokote, Aircell, and Thermobestos materials were:

  • Broken or cut during pipe removal and replacement
  • Sanded or scraped during surface preparation before repainting or covering
  • Removed by hand without respiratory protection or containment
  • Disposed of without hazardous waste protocols

Diseases Caused by Asbestos Exposure

Asbestos causes several serious and frequently fatal diseases:

Mesothelioma

  • Cancer of the pleural lining (lung), peritoneal lining (abdomen), or pericardium (heart)
  • Causally linked to asbestos exposure with no established safe exposure threshold
  • Median survival typically 12 to 21 months after diagnosis
  • Develops decades after exposure; frequently diagnosed at an advanced stage

Asbestosis

  • Progressive fibrotic lung disease caused by accumulation of asbestos fibers in lung tissue
  • Produces irreversible scarring that reduces lung capacity and oxygen exchange
  • Disabling over time, with no treatment that reverses the underlying fibrosis
  • Qualifies as a VA presumptive condition and supports both civil litigation and trust fund claims

Lung Cancer

  • Asbestos exposure causes lung cancer independent of smoking history
  • Smokers with asbestos exposure face multiplicative — not merely additive — risk increases
  • Qualifies for VA presumptive service connection under 38 C.F.R. § 3.309(d)
  • Supports civil litigation against product manufacturers and trust fund claims

Pleural Disease

  • Pleural plaques, pleural effusions, and diffuse pleural thickening are markers of asbestos exposure
  • Pleural plaques alone are not disabling but document prior exposure and support VA claims
