NATO's 2027 exercise calendar, maintained from the planning stage onward. Each entry is labelled confirmed or projected; each change is dated and sourced.


TL;DR: The triennial Steadfast Defender series returns in 2027.
Confirmed — Steadfast Defender 27 (main planning conference held June 2026; SD24 precedent: ~90,000 personnel); Steadfast Dart 27, the Allied Reaction Force deployment to North Macedonia within the SD27 series; NATO Tiger Meet 2027 at Gioia del Colle, Italy.
Projected — eighteen recurring series with established cadences, from Joint Viking (Norway, March) through Formidable Shield and BALTOPS to Steadfast Noon (October) and Cyber Coalition (November–December). None is yet announced; the calendar states each projection basis.
Off-cycle in 2027 — Nordic Response (biennial, next 2028), Estonia's Siil (last held 2025), and Sweden's Aurora fall outside the 2027 window on their stated cadences.
Standing activities — Baltic, Eastern, and Arctic Sentry are expected to continue into 2027, subject to SACEUR posture decisions.

Scope

NATO's exercise calendar is published incrementally: planning conferences run 12–18 months ahead of execution, and dates are confirmed piecemeal by SHAPE and national ministries, winter drills first. A complete official 2027 picture will not exist until well into the year.

This page collates what is on record now. Entries are labelled confirmed when a NATO command or national ministry has named the exercise, projected when only a series cadence supports them. Confirmations are logged with source and date as they land. The 2026 guide covers the current year.


2027 NATO Exercise Calendar at a Glance

Entries are grouped by evidence: scheduled, confirmed with dates pending, or projected from series cadence. They move up as ministries publish; each move is recorded in the change log. Map pins carry the same labels; the Gantt timeline view follows once dated entries exist — likely around the turn of the year, when SHAPE's calendar is published.

Flagship Drills to Watch in 2027

The Steadfast Defender Year

STEADFAST DEFENDER 27 (dates TBC, alliance-wide). The triennial flagship returns. NATO's Joint Warfare Centre hosted the main planning conference in June 2026; SHAPE schedules and conducts the exercise as a federation of national and NATO drills involving all NATO headquarters, across multiple areas of operational responsibility. The precedent is Steadfast Defender 24 — roughly 90,000 personnel across a January-to-May campaign from the North Atlantic to the eastern flank. Whether 2027 matches that scale is open: the planning language emphasises linked national exercises over a single monolithic deployment, the same structure as the 2026 season. The national building blocks — Germany's Quadriga cluster, Romania's Dacia-linked programme, the Nordic winter drills — are likely to declare their SD27 affiliations one by one over the autumn.

STEADFAST DART 27 (dates TBC, North Macedonia). The first named building block. A SHAPE, JFC Naples and NATO Rapid Deployable Corps Italy delegation surveyed the Krivolak training area, Pepelishte camp and Petrovec barracks in June 2025, per the North Macedonian General Staff — the Allied Reaction Force deployment exercise moves to the southern flank after its 2026 iteration ran into Germany under JFC Brunssum. That rotation is the tell: the ARF construct is being exercised against a different reinforcement axis each cycle, and a Skopje-hosted iteration puts the load on the Adriatic and North Macedonian corridors rather than the North Sea ports.

The Recurring Backbone

JOINT VIKING 27 (March window, projected). Norway's biennial odd-year winter defence exercise is due on its cadence — Joint Viking 25 brought about 10,000 personnel from nine nations to Troms. It is not yet announced, and the 2027 iteration carries a live question: the scale of US participation, which analysts have flagged as uncertain since the 2025 iteration. How Oslo frames the announcement will be read as a posture signal well beyond Norway.

NATO TIGER MEET 2027 (dates TBC, Italy). The Tiger Association has confirmed Gioia del Colle Air Base as host — the Italian Eurofighter wing's home, which last hosted in 2023. Dates typically land in the May window.

FORMIDABLE SHIELD 27 (May window, projected). Europe's largest integrated air and missile defence live-fire exercise runs on a biennial odd-year cadence — 2021, 2023, 2025 — which puts the next iteration in 2027. The 2025 edition brought about 7,000 personnel, 17 ships and 11 nations to the Hebrides and Andøya ranges for live intercepts against subsonic, supersonic and ballistic targets. No announcement yet; given the pace of European GBAD procurement between iterations, the 2027 shot list will be read closely.

The rest of the backbone runs on published cadences — none yet announced for 2027, each listed in the calendar with its basis:

Winter–spring — DYNAMIC FRONT (fires), DYNAMIC MANTA (Mediterranean ASW), SEA SHIELD (Black Sea), AFRICAN LION, SPRING STORM (Estonia), DYNAMIC MONGOOSE (North Atlantic ASW), FORMIDABLE SHIELD (IAMD live-fire) and the SWORD umbrella, the US Army's signature exercise in Europe.

Summer — BALTOPS at its 56th iteration, RAMSTEIN FLAG, SEA BREEZE (annual since 1997), the NEPTUNE STRIKE carrier series, and Germany's QUADRIGA cluster.

Autumn — REPMUS unmanned-systems experimentation (Portugal), NAMEJS (Latvia), the STEADFAST NOON nuclear-deterrence serial, and CYBER COALITION (Tallinn).

The Sentry Activities

Baltic Sentry (since January 2025), Eastern Sentry (since September 2025) and Arctic Sentry (since February 2026) are persistent vigilance activities, not exercises — they do not appear in the calendar rows. All three are expected to continue into 2027, subject to SACEUR posture decisions; any formal change will be logged here.


How This Calendar Works

Three evidence tiers. Scheduled means official dates are published. Confirmed, dates pending means a NATO command or national ministry has named the exercise — a planning conference, a site reconnaissance, a host announcement — but not dated it. Projected from cycle means the entry rests only on a stated series cadence; it is a forecast, labelled as one.

Provenance per record. Every entry in the underlying dataset carries its evidence basis, the naming source, and a last-verified date. Sources are NATO commands (SHAPE, JWC, AIRCOM, MARCOM, STRIKFORNATO), national defence ministries, and the units themselves — never aggregators.

Update discipline. Confirmations are folded in within 24 hours of an official release; every change is logged below with its date. A wrong projection is corrected and the correction logged — the prior state stays on the record.

Change Log

16 August 2026 — Page opened. Three confirmed anchors (Steadfast Defender 27, Steadfast Dart 27, NATO Tiger Meet 2027), eighteen cycle-based projections, three persistent activities carried as expected continuations.


Frequently Asked Questions

When will Steadfast Defender 27 take place?

NATO has not published dates. The main planning conference concluded at the Joint Warfare Centre in June 2026. The 2024 iteration ran January to May; if SD27 follows that pattern the first movements would begin in the opening weeks of 2027, but that timing is a projection, not an announcement.

How big will Steadfast Defender 27 be?

Unknown. Steadfast Defender 24 involved roughly 90,000 personnel across months of linked drills. NATO describes SD27 as a federation of national and NATO exercises involving all NATO headquarters — language that points to a distributed campaign rather than a single mass deployment. Participation figures will be added as commands release them.

Which 2027 exercises are already confirmed?

As of 16 August 2026: Steadfast Defender 27 (planning conference held), Steadfast Dart 27 (North Macedonia site reconnaissance completed June 2025), and NATO Tiger Meet 2027 (host base Gioia del Colle announced). Everything else in the calendar is projected from series cadence and labelled accordingly.

What does “projected from cycle” mean?

The exercise has not been announced for 2027 — but its series runs on a stated rhythm (annual, biennial) that puts an iteration in the 2027 window. The calendar names that basis for each entry. Projections can be wrong; when one is, the correction is logged, not overwritten.

Where is the 2026 exercise calendar?

The NATO Exercises 2026 guide covers the current year, with live map, Gantt timeline and calendar table. The 2027 calendar adds the confirmed-versus-projected labels and the change log; its map is live, and the timeline view is added once dated entries exist.
