Which defense advantages are strengthening—and which are becoming more fragile?

Production-representative Collaborative Combat Aircraft contracts and an open autonomy architecture create a credible path, but no operational squadrons or sustained output are yet public.

Large Indo-Pacific exercises are practicing allied, distributed, and austere operations.

The U.S. still holds advantages in low-observable aircraft, mission systems, allies, and operational integration.

The public record cannot compare signatures, electronic-warfare performance, combat-coded availability, or weapons sufficiency symmetrically.

Private repair capacity has improved since 2019, and the Navy is investing in maintenance and industrial capacity.

Naval strategy relies on allied access and a joint ecosystem while pursuing robotic and autonomous systems.

U.S. and allied undersea performance, sensing, bases, and repair access could preserve mission advantage despite platform-count trends.

No symmetric public measure resolves submarine acoustic performance, detection probability, or combat-effective availability.

The fiscal 2026 request spans PrSM, JASSM, LRASM, SM-6, and Tomahawk, while direct investment targets the shared solid-rocket-motor bottleneck.

New entrant and low-cost cruise-missile efforts could broaden the supplier base, but tests and military utility assessments precede large production.

China fields multiple regional-range ballistic, cruise, and hypersonic systems at theater-relevant ranges.

Navy hypersonic integration is delayed, production is below goal, and PrSM Increment 2 early operational deliveries are not expected before fiscal 2029.

The final GPS III launch completed a 32-satellite active constellation and demonstrated a launch-provider change in under seven weeks.

Tranche 1 transport satellites are in launch and integration, with initial warfighting capability planned for 2027.

GAO found readiness, unplanned-work, schedule-transparency, and workforce gaps that could delay conversion of satellites into usable mission capability.

No public exercise demonstrates full mission restoration after representative satellite and ground-segment loss.

CMMC, zero-trust plans, public-private collaboration, and electronic-warfare reprogramming investments are expanding.

Joint advisories provide detailed observed tactics and mitigations across allied networks.

Implementation gaps remain across the defense industrial base and major DOD systems.

Cyber effects, accesses, and electronic-warfare performance are inherently incomplete in public reporting.

Eight leading AI companies have agreements to make advanced capabilities available on classified networks.

The NAIRR is expanding access to compute, data, models, and expertise across U.S. research teams.

PRC access to frontier accelerators remains constrained while efficiency and domestic alternatives improve.

Public benchmarks and deployment monitoring remain immature and can diverge sharply from real-world performance.

Pacific Deterrence Initiative projects add fuel infrastructure at Yokota, Wake Island, and Camp Butler.

Services have some organic and allied repair access, and exercises increasingly integrate joint and allied participants.

Fuel storage and delivery risks, pre-positioning management problems, and battle-damage repair throughput remain unresolved.

Foreign military sales and release decisions can still take months or years.

Record planned U.S. generation additions and installation microgrid projects should improve capacity and local resilience.

Pacific fuel-storage and distribution projects target known regional gaps.

U.S. refining capacity declined in 2025, and public data do not resolve priority military-fuel coverage by theater node.

China's generation build is large, but imported crude and seaborne transport remain major dependencies.

U.S. NdPr oxide output reached a record and commercial-equipment magnet manufacturing began in December 2025.

Public finance and Defense Production Act investments are expanding mineral, magnet, and solid-rocket-motor capacity.

Commitments still exceed disbursement and several announced projects lack accepted output, qualification coverage, or independent feedstock.

Allied supply materially mitigates some cobalt, germanium, and titanium pathways but can retain shared upstream exposure.

Recurring joint and allied exercises create opportunities to convert experience into repeatable mission performance.

New guidance emphasizes linking training to mission priorities and organizational performance.

Civilian workforce reductions, instructor shortages, and specific technical vacancies may erode the experience base despite aggregate recruiting gains.

Neither side publishes comparable complete-team performance after communications, logistics, infrastructure, and key-personnel loss.
