## Summary

Four months after [New START lapsed](/hi/n/new-start-expiry-aftermath), [Russia](/hi/entity/russia) has not
broken out. Russian officials said Moscow would keep observing the central limits — 1,550
warheads on 700 delivery vehicles — so long as [Washington](/hi/entity/united-states) does. US
assessments (CRS, May 2026) confirm no large-scale warhead increase. But the
[latent capacity remains](/hi/head/what-theyre-not-saying): analysts estimate Russia could upload
hundreds of non-deployed warheads, lifting its deployed force by up to ~60%. Speed varies
by leg — bombers in hours, submarines in months, ICBM reconfiguration in years. The
[consensus read](/hi/head/the-long-game) (War on the Rocks, Bulletin) is that Russian
modernization mostly replaces Soviet-era systems rather than expanding numbers, leaving
little near-term incentive to sprint — but the option is now legally unconstrained.

## By the numbers

- ~60% — potential increase in deployed warheads if Russia fully uploads its reserve.
- 1,550 / 700 — the New START limits Moscow says it will still observe.
- Hours to years — upload time depending on bomber, submarine or ICBM.
- 4 months — since the treaty lapsed with no Russian breakout.

## Why it matters

The danger is no longer a treaty cap but an opaque, reversible hedge. Without inspections,
Washington must infer Russian intentions from sparse signals, and any US upload to match a
perceived Russian move would be equally unverifiable — the classic action–reaction spiral
arms control was built to dampen.

## What to watch

- Satellite/intelligence signs of warhead loading at bomber or ICBM bases.
- Any US decision to upload first, citing the China threat.
- Russian statements tying restraint to US missile-defence ([Golden Dome](/hi/n/golden-dome-architecture-2026)) moves.

### defence-analyst
- **War on the Rocks** (United States, en) — Argues Russia is 'running to stand still': its modernization replaces aging Soviet systems rather than expanding numbers, and a sprint past New START limits would be costly and slow. Plays down imminent breakout despite the treaty's lapse.
  > "Russian modernization largely sustains parity rather than building toward it; a rapid breakout would be expensive and offer little strategic gain."

- **Bulletin of the Atomic Scientists** (United States, en) — The Nuclear Notebook's 2026 Russia estimate: catalogues delivery systems and warhead allocation and quantifies the upload reserve. Treats the treaty lapse as removing a ceiling Russia had little near-term incentive to exceed.
  > "Russia retains a substantial reserve of non-deployed warheads that could, in principle, be uploaded onto existing delivery systems."
