12 Big Naval Maritime Contracts in the Last Year That Are Reshaping Shipyards and Fleet Readiness

Naval contracting has been unusually concentrated lately. A small number of awards are doing most of the work shaping shipyard capacity, submarine industrial base pacing, and fleet sustainment throughput. The list below stays tight on “big and documented” contracts or contract actions over roughly the last 12 months, then summarizes why each one matters to stakeholders.

12 Big Naval Maritime Contracts in the Last Year First 6 contracts and contract actions with the clearest global impact on yards, submarines, and sustainment
# Contract Value Covers Stakeholders
1
Australia general purpose frigates selection
Buyer: Australia • Supplier: Mitsubishi Heavy Industries
A$10B
Announced Aug 2025
Selection of the Mogami-class frigate design for Australia’s future general purpose frigates, with early ships built in Japan and a larger build component planned for Australia.
Key programs then cascade into combat system integration, local build transfer, and long lead procurement.
A large, export-signaling surface combatant award that drives supplier commitments and defines yard loading and workforce planning years ahead.
This is one of the biggest recent surface combatant awards by value in the Indo-Pacific.
Surface combatants Industrial base
2
Norway Type 26 frigates partnership
Buyer: Norway • Supplier: UK and BAE Systems led industrial team
£10B
Announced Aug 2025
Strategic partnership and agreement for Norway to acquire British-designed Type 26 anti-submarine frigates, tied to industrial participation and long-term cooperation.
Exact ship count and timeline details are typically refined as the program matures.
A major European warship export by value with multi-year yard and supplier implications, particularly for anti-submarine warfare capability demand. ASW Export shipbuilding
3
Virginia-class submarines two-ship modification
Buyer: US Navy • Supplier: General Dynamics Electric Boat
$12.4B
Announced Apr 2025
Contract modification for construction of two FY2024 Virginia-class submarines under the existing Virginia-class Block V contract framework.
Large value reflects multi-year construction scope and complex subcontracting across the submarine industrial base.
One of the clearest “big money” signals for submarine workload and vendor demand, with direct implications for workforce, long lead materials, and supplier throughput. Sub industrial base Long lead demand
4
Columbia-class advance procurement and early construction
Buyer: US Navy • Supplier: General Dynamics Electric Boat
$2.28B
Announced Nov 2025
Contract modification for advance procurement and advance construction on multiple Columbia-class SSBN hulls, plus additional program execution support.
This is the kind of action that locks in supplier work before full-year funding is in hand.
Columbia is the top US Navy acquisition priority, so these actions influence supplier confidence, capacity investment, and critical path material ordering. Strategic deterrent Supplier lock-in
5
John Lewis-class fleet oilers T-AO 215 and 216
Buyer: US Navy • Supplier: General Dynamics NASSCO
$1.7B
Announced Nov 2025
Contract award to construct two additional John Lewis-class fleet replenishment oilers, extending the oiler production line.
Replenishment hulls are operational tempo enablers, so cadence matters as much as the ship count.
A high-signal logistics award that drives steady yard workload and supplier flow, and it links directly to fleet sustainment capacity. Logistics hulls Serial production
6
DLA Maritime ship manufacturing acceleration contract
Buyer: Defense Logistics Agency Maritime
$5B
Announced May to Jun 2025
A multi-award contract intended to speed ship manufacturing and improve supply support for key Navy platforms, tied to accelerated procurement of equipment and services.
This is industrial-base acceleration more than a single-hull purchase.
It is a “supply chain throughput” lever that affects multiple programs at once, which is why it shows up as a big stakeholder signal even without a new hull attached. Supply chain Multi-program impact
7
Virginia class long lead and preliminary construction modification
Buyer: US Navy • Supplier: General Dynamics Electric Boat
$1.85B
Announced Jul 2025
Contract modification focused on long lead material and preliminary construction efforts supporting Virginia class submarine production.
These actions pull supplier work forward and reduce the chance of the build plan stalling later due to missing critical parts.
A direct read on submarine industrial base throughput and vendor capacity planning, especially for constrained components and multi-tier suppliers.
Stakeholders watch these mods because they often translate into real purchase orders and shop loading.
Sub industrial base Long lead
8
US Navy nuclear attack submarine maintenance modernization contract
Buyer: US Navy • Multiple awardees • Public shipyards support
Up to $1.9B
Announced Sep 2025
Multiple award contract for repair, maintenance, and modernization work on nuclear powered attack submarines supporting scheduled maintenance availabilities at the Navy’s public shipyards.
This is sustainment capacity, not new hulls, but it directly affects fleet availability.
A major “availability throughput” lever. It signals how the Navy is spreading workload, managing surge capacity, and stabilizing execution for submarine maintenance windows. Sustainment Public yards
9
Two frigates agreement via TAIS and Barzan Holdings for Indonesia
Buyer: Indonesia (via Barzan) • Supplier: TAIS consortium (Turkey)
About $1B
Signed Jan 2026
Agreement covering procurement of two frigates for the Indonesian Navy, signed during DIMDEX 2026.
Structure involves a buyer-side entity and a shipbuilding consortium, with the program tied to Turkey’s export naval pipeline.
A high-signal export combatant deal that pulls in propulsion, combat system integration, and multi-year supplier commitments. Export shipbuilding Frigates
10
Naval nuclear propulsion components contract
Buyer: US Navy • Supplier: Bechtel Plant Machinery
$812.1M
Awarded Jan 2026
Cost plus fixed fee contract for naval nuclear propulsion components, with work extending into the next decade.
These components underpin both carrier and submarine propulsion plant pipelines.
A foundational industrial base award. It signals continuity in the nuclear propulsion supply chain that underwrites submarine and carrier schedules. Nuclear propulsion Long duration
11
Philippines two new frigates procurement
Buyer: Philippines DND • Supplier: HD Hyundai Heavy Industries
₱34B (about $585M)
Announced Dec 2025 to Jan 2026
Procurement of two additional frigates for the Philippine Navy, following issuance of a notice of award and reporting around contract signing steps.
Adds to the Philippines’ surface fleet modernization and drives a multi-year build and integration effort.
A notable Indo-Pacific surface combatant buy with regional security relevance and shipbuilder orderbook implications. Indo Pacific Surface combatants
12
AUKUS SSN AUKUS nuclear propulsion long lead items
Buyer: Australia • Supplier: United Kingdom industrial base
$310M
Announced Feb 2026
Payment for acquisition of long lead items from the UK to support manufacture of critical components for future SSN AUKUS nuclear propulsion systems planned for build at Osborne.
This is early tangible spend that advances the SSN AUKUS industrial pathway.
A high-signal AUKUS execution milestone. It informs supplier confidence and early production planning even though it is smaller than the headline shipyard build numbers. AUKUS Long lead

Taken together, these awards show where naval money is really concentrating: submarines and nuclear propulsion capacity, a steady push to add sustainment throughput, and a handful of large surface combatant buys that lock in yard loading for years. For stakeholders, the useful signal is not just the headline value, but what each contract implies about bottlenecks, supplier commitments, and the timing pressure that will show up later in maintenance and delivery schedules.

  • Submarines and nuclear propulsion continue to pull long lead spend forward and anchor multi year supplier capacity decisions
  • Sustainment and availability throughput is getting funded as a constraint, not treated as an afterthought
  • Export frigate deals are shaping regional orderbooks and combat system integration pipelines
  • The industrial base theme keeps repeating: the winners are the programs that can actually turn funding into parts, labor, and on time test completion
