Navy Opens Public Comment on Historic Preservation Pact for Bremerton Waterfront Overhaul and Hammerhead Crane Removal

The U.S. Navy launched a formal 21-day public comment period on September 28, 2026, inviting community review of a Draft Memorandum of Agreement governing adverse effects on historic properties at Naval Base Kitsap-Bremerton. The agreement, negotiated under Section 106 of the National Historic Preservation Act, outlines required mitigation measures for extensive waterfront industrial reconfigurations at Puget Sound Naval Shipyard and Intermediate Maintenance Facility. The overarching federal undertaking involves constructing a modern multi-mission dry dock engineered to maintain nuclear-powered aircraft carriers and attack submarines for future decades. That construction requires the demolition of several contributing resources to the shipyard historic district, most notably the towering 250-ton Hammerhead Crane that has stood along Pier 6 since 1933. The comment window remains open through October 19, 2026, providing Kitsap County residents, civic organizations, and shipyard workers a direct opportunity to shape how the military preserves the maritime heritage of Sinclair Inlet during essential fleet modernization and waterfront transformation.

Federal Consultation Under the National Historic Preservation Act

The consultation process follows federal statutory requirements established in Section 106 of the National Historic Preservation Act of 1966, codified under Title 54 of the United States Code. Under these legal mandates, federal agencies must evaluate the effects of their undertakings on historic properties and provide the Advisory Council on Historic Preservation a reasonable opportunity to comment. Naval Facilities Engineering Systems Command Northwest initiated formal discussions with the Washington Department of Archaeology and Historic Preservation, sovereign tribal governments, and local historic preservation commissions to identify properties listed in or eligible for the National Register of Historic Places.

Puget Sound Naval Shipyard was established in 1891 as Naval Station Puget Sound and was designated a National Historic Landmark District in 1992. The district encompasses more than eighty contributing historic buildings, marine railways, dry docks, and waterfront structures that reflect naval expansion through World War II. Because constructing the proposed multi-mission dry dock and replacing adjacent piers will alter or demolish contributing features, the Navy determined that the project will cause adverse effects on the landmark district. Section 106 does not forbid the removal of historic structures, but it mandates open consultation to seek practical ways to avoid, minimize, or mitigate the loss. The publication of the Draft Memorandum of Agreement represents the formal mechanism through which the Navy, the State Historic Preservation Officer, and consulting parties codify binding mitigation obligations before construction commences.

Engineering Realities and Operational Obsolescence of the 1933 Hammerhead Crane

The centerpiece of the historic dispute is Crane 28, commonly recognized across Kitsap County as the 250-ton Hammerhead Crane on Pier 6. Built in 1933 by the Dravo Contracting Company of Pittsburgh, Pennsylvania, at a contracted cost of $1.06 million, the massive steel cantilever structure served as the primary heavy-lift mechanism for Pacific Fleet capital warships between World War I and the Cold War. Dravo engineers configured the machine with a 250-foot counterbalanced horizontal boom capable of revolving 360 degrees atop four massive lattice-steel legs. During the 1930s and 1940s, the crane hoisted 16-inch naval artillery rifles, armored gun turrets, and protective deck plating aboard battleships, including ships repaired following the attack on Pearl Harbor.

Despite its historic significance, the crane has stood inactive for decades as shipyard operations shifted to agile rail-mounted portal cranes and floating heavy-lift barges. Structural engineering assessments performed for the project environmental review documented severe structural deterioration across the boom and supporting tower. Over nine decades of exposure to salt air and marine fog produced extensive pack rust across critical gussets. The steel framing lacks modern seismic ductility, creating significant collapse hazards for adjacent berthing spaces during a major earthquake. Furthermore, the structure is coated in thick layers of deteriorating lead paint and contains asbestos insulation that would require multimillion-dollar remediation. More critically, the crane sits directly within the construction footprint of the planned multi-mission dry dock, physically blocking dredging equipment required to establish deep-water foundations.

Binding Mitigation Commitments Outlined in the Draft Agreement

The Draft Memorandum of Agreement outlines specific preservation actions designed to record and commemorate the engineering history of Pier 6 before deconstruction begins. Central to the pact is Level I documentation under the Historic American Engineering Record, a program administered by the National Park Service. The Navy must produce archival large-format 4x5 black-and-white film photographs capturing overall elevations, mechanical details, and structural joinery, along with measured drawings and an exhaustive historical narrative deposited in the Library of Congress. The documentation protocol requires collaboration between Naval History and Heritage Command historians and National Park Service curators to produce calibrated line drawings generated from high-density point clouds.

Beyond archival records, the draft agreement establishes tangible community mitigation measures within Bremerton. The Navy will salvage key mechanical artifacts, such as the operator cab control console, cast iron builder plates, gear mechanisms, and primary lifting blocks. These artifacts will undergo stabilization and lead paint encapsulation before transfer to local cultural repositories, with primary custody assigned to the Puget Sound Navy Museum located adjacent to the shipyard boundary in downtown Bremerton. The military will also fund the design, fabrication, and installation of permanent interpretive wayside exhibits along public waterfront walkways near the ferry terminal. To ensure educational access for younger generations, the Navy committed to generating an interactive three-dimensional digital model using terrestrial laser scanning data, enabling virtual walkthroughs of the historic machinery and crane cab.

Strategic Drivers Behind the Shipyard Infrastructure Optimization Program

The waterfront reconfiguration in Bremerton is part of the Department of the Navy nationwide Shipyard Infrastructure Optimization Program, a comprehensive twenty-year initiative designed to recapitalize public naval shipyards in Hawaii, Maine, Virginia, and Washington. A detailed evaluation by the Government Accountability Office confirmed that modernizing the four public shipyards represents an investment exceeding $200 billion across a multi-decade life cycle. Puget Sound Naval Shipyard operates as the primary West Coast overhaul facility for nuclear aircraft carriers and submarines, employing more than fourteen thousand civilian personnel and military service members.

The Government Accountability Office identified aging dry docks and deteriorated waterfront utility distributions as the primary vulnerability in Navy carrier maintenance availability. Dry Dock 6, constructed in 1962, is currently the only operational dry dock on the West Coast capable of dry docking a Nimitz-class aircraft carrier. However, the Navy fleet transition to newer Gerald R. Ford-class carriers requires deeper basin draft, enhanced electrical capacity, and reconfigured utility tunnels that existing facilities cannot accommodate. The planned multi-mission dry dock will feature an advanced seismic perimeter cutoff wall, heavy-capacity gantry cranes, and high-efficiency pumping systems capable of dewatering millions of gallons in under three hours. Navy planners determined that building this facility at Bremerton is essential to prevent severe maintenance backlogs that could idle Pacific Fleet carrier strike groups, balancing statutory heritage obligations against long-term national defense mandates across the Indo-Pacific theatre.

Treaty Fishing Protections and Sinclair Inlet Environmental Controls

Industrial operations at Naval Base Kitsap-Bremerton directly affect the marine waters of Sinclair Inlet, which form part of the usual and accustomed fishing grounds protected under the 1855 Treaty of Point Elliott. In June 2026, the Navy finalized a related Memorandum of Agreement with the Suquamish Tribe to address adverse impacts to tribal fisheries caused by in-water construction, pile driving, and sediment dredging. Sinclair Inlet provides vital nursery habitat for juvenile Puget Sound chinook, bull trout, and steelhead trout protected under the federal Endangered Species Act. Under the government-to-government agreement between the Navy and the Suquamish Tribe, the military committed $21 million in environmental mitigation and fisheries enhancement funding to offset lost fishing access.

The historic preservation agreement operates alongside these environmental covenants to ensure demolition activities do not compound ecological harm in Puget Sound. In-water demolition and pier deconstruction will be strictly restricted to approved regulatory fish work windows, protecting juvenile salmonids and forage fish spawning cycles. Contractors must install continuous turbidity curtains and acoustic bubble curtains during pile removal to suppress underwater pressure waves that injure marine mammals and salmon. Contaminated sediments excavated near Pier 6 will be transported to licensed upland disposal facilities rather than redistributed in local waters. Tribal fishers operating gillnet vessels will receive real-time scheduling notices regarding marine vessel movements and barge moorings to prevent gear entanglements and operational collisions near naval security perimeters.

Public Comment Deadlines and Civic Influence on the Final Historic Covenant

For Bremerton residents, the impending removal of the Hammerhead Crane marks a profound visual change to the regional landscape. The structure has dominated the Sinclair Inlet waterfront for over nine decades, greeting ferry passengers arriving from Seattle and serving as a geographic touchstone for residents in Port Orchard and the Manette neighborhood. Preserving its institutional memory is a shared concern among civic leaders and historical preservation advocates who want Bremerton naval heritage honored amidst rapid technological modernization. The Bremerton Historic Preservation Commission and the Kitsap County Historical Society have followed waterfront planning closely, advocating for prominent physical memorials along the Louis Mentor Boardwalk.

Public participation remains a vital stage of the Section 106 review before federal officials execute the final binding covenant. Citizens, historians, civic organizations, and shipyard retirees have until October 19, 2026, to submit formal comments on the Draft Memorandum of Agreement. Written comments can be submitted via email directly to the Navy at [email protected]. Full text copies of the draft agreement, along with historical assessment reports, can be examined on the official project website at Bremerton Waterfront Improvements EIS. Local civic groups stress that incorporating salvaged artifacts into public spaces preserves Bremerton working-class identity while supporting downtown revitalization. Federal officials will review public feedback before finalizing the agreement and proceeding with the final Record of Decision for waterfront construction.
