Allied Nations Tackle Aging Frigate Fleets: New Zealand’s Joint Procurement Talks and the UK’s Shrinking Surface Fleet
5/7/2026, 7:18:14 AM
New Zealand Launches Joint Frigate Replacement Talks
New Zealand’s defence minister, Chris Penk, announced on 7 May 2026 that Wellington has opened formal discussions with Australia and Britain to replace its two ageing Anzac-class frigates, HMNZS Te Kaha (commissioned 1997) and HMNZS Te Mana (commissioned 1999). The business case will evaluate Japan’s Mogami-class frigate—already selected by Australia—and Britain’s Type 31 frigate. A preferred-path recommendation is slated for the government by the end of 2027, forming part of the 2025 Defence Capability Plan.
UK’s Surface Fleet Shrinks to Five Operational Frigates
In the United Kingdom, the Royal Navy’s active frigate fleet has fallen to five operational Type 23 vessels after HMS Iron Duke was effectively taken out of service. The ship, which underwent a £103 million, 49-month refit, has not sailed since October 2025. Defence Minister Luke Pollard cited the platform’s remaining service life, conversion time, and competing priorities as reasons the project “did not justify the additional cost or extended period out of service.”
Background & Context
New Zealand’s plan follows years of “systemic underspend” and a commitment to lift defence spending, aiming to protect sea lanes, support Pacific security, and improve disaster response. The UK’s decision aligns with a broader “hybrid” navy strategy outlined in the Strategic Defence Review, which seeks to integrate crewed ships, drones, and autonomous systems while accelerating the introduction of eight Type 26 anti-submarine frigates and five Type 31 general-purpose frigates.

- Nov 2025 – UK cancels HMS Iron Duke conversion.
- Oct 2025 – HMS Iron Duke ceases sea operations.
- 7 May 2026 – NZ announces joint frigate talks.
- Mid-2030s – NZ’s Anzac frigates expected to reach end of design life.
- 2029-2039 – NZ earmarks indicative investment for replacements.
- 2025-2030 – First Type 26 hulls to enter service.
- 2026-2027 – Four Type 31 hulls have steel cut; fifth keel laying pending.
Data & Statistics
- Two Anzac frigates (1997, 1999) form NZ’s main maritime combat capability.
- NZ’s replacement programme listed as an indicative investment for 2029-2039.
- UK now operates five Type 23 frigates after Iron Duke’s withdrawal.
- Iron Duke’s refit cost £103 million; required 49 months and 1.7 million man-hours.
- UK plans eight Type 26 and five Type 31 frigates; four Type 31 hulls already have steel cut.
Why It Matters
For New Zealand, modern frigates are essential to safeguard Pacific sea lanes and respond to natural disasters. The UK’s reduced surface fleet narrows its capacity to meet NATO commitments in the North Atlantic, accelerating reliance on new hulls and autonomous platforms to maintain maritime security.
Official Statements & Responses
Penk emphasised that partnering with Australia and Britain would “ensure interoperability and potential efficiencies.” Pollard argued that the Iron Duke conversion “did not justify the additional cost or extended period out of service.” The MoD spokesperson highlighted a “new hybrid Navy” built through the Strategic Defence Review, while First Sea Lord Sir Gwyn Jenkins described the modernisation as creating a hybrid force that blends crewed ships with drones. Al Carns noted increased Russian submarine activity in the English Channel, underscoring the need for vigilant patrols.
Conflicting Reports & Gaps
The Ministry of Defence has not issued an official decommissioning notice for HMS Iron Duke, stating that out-of-service dates remain under continual review.

What’s Next
New Zealand expects a preferred-path recommendation by late 2027, after which procurement decisions will follow. The UK anticipates steel-cut milestones for the remaining Type 31 hulls and keel-layings for the final Type 26 ships through the mid-2030s, while assessing interim measures to sustain surface-fleet commitments before the new vessels become operational.
