Boston CAG-1
Last updated July 11, 2026
The Boston CAG-1 was a class of U.S. Navy cruisers from the asbestos era, led by USS Boston (CAG-1). Its 2 ships used asbestos-containing insulation throughout the engineering plant, and veterans who served aboard Boston CAG-1 vessels — especially in engineering ratings — may have been exposed to asbestos fibers.
About the Boston CAG-1
- 2 ships in the class
- Hull numbers span CAG-1 to CAG-2
- Lead ship: USS Boston (CAG-1)
- 2 ships in this class carry recorded service or disposition notes (see the roster below)
Asbestos Exposure Aboard Boston CAG-1 Ships
Asbestos was the standard thermal insulation material aboard U.S. Navy cruisers built before approximately 1980. On ships of this type, asbestos-containing materials were concentrated in the areas below.
- Main propulsion machinery spaces — turbine and boiler insulation
- Missile launcher machinery rooms — thermal and acoustic insulation
- Combat information center (CIC) — overhead insulation on some classes
- Steam piping throughout the ship — pipe wrap and expansion joints
- Gaskets at every flange in the engineering plant
- Electrical cable runs — asbestos-braided cable on older vessels
Heavy cruisers of the Baltimore class (commissioned 1943–1946) through the Long Beach (CGN-9, 1961, the first nuclear surface combatant) and Leahy-class DLGs represent the span of asbestos use in cruisers.

At-Risk Ratings Aboard Boston CAG-1 Ships
The following ratings had regular contact with asbestos-containing materials aboard cruisers of this era. If you served in one of these ratings, document it when filing a VA disability or asbestos trust fund claim.
Ships in the Boston CAG-1 (2 vessels)
| Ship Name | Hull No. | Notes |
|---|---|---|
| USS Boston | CAG-1 | Converted from heavy cruisers; all asbestos era |
| USS Canberra | CAG-2 | Converted from heavy cruisers; all asbestos era |
VA Benefits & Legal Options for Boston CAG-1 Veterans
Veterans diagnosed with mesothelioma, asbestosis, pleural plaques, or asbestos-related lung cancer who served aboard Boston CAG-1 ships may be eligible for:
- VA disability compensation — monthly benefit; requires diagnosis plus evidence of shipboard service. No manufacturer identification needed.
- Asbestos trust fund claims — lump-sum payments from trusts funded by bankrupt asbestos manufacturers (Johns-Manville, Owens Corning, and others). Requires identifying specific products used aboard.
These two paths are not mutually exclusive. Many veterans pursue both.

Frequently Asked Questions
Did Boston CAG-1 ships use asbestos?
Yes. The Boston CAG-1 was built during the era when asbestos was the standard insulation material in U.S. naval construction. Engineering spaces aboard these vessels contained asbestos pipe lagging, boiler block insulation, gaskets, and valve packing. Veterans who worked in boiler rooms, engine rooms, or repair roles had the highest likelihood of exposure.
How do I prove I served aboard a Boston CAG-1 ship for a VA claim?
Your DD-214 (Certificate of Release or Discharge from Active Duty) lists your ship assignments. Additional documentation includes ship deck logs (available from the National Archives), official orders, and buddy statements from fellow crew members. A Veterans Service Organization (VSO) can help you gather and submit this evidence at no cost.
What asbestos products were used aboard Boston CAG-1 ships?
Common asbestos products used in U.S. Navy cruisers of this era included Kaylo pipe insulation (Owens-Illinois), Unibestos block insulation (Pittsburgh Corning), 85% magnesia pipe covering (various manufacturers), Flexitallic spiral-wound gaskets, and Johns-Manville pipe covering. A mesothelioma attorney who specializes in Navy claims maintains detailed product-identification databases for specific ship classes.
Did You Serve Aboard Boston CAG-1?
If you or a family member served aboard Boston CAG-1, you may have been exposed to asbestos. Sharing your service information is completely voluntary and may help build the historical record of shipboard exposure — information that can be valuable in VA disability and asbestos trust fund claims.
