Operations at sea

Rocket launching

The areas where spent rocket stages, boosters and fairings are expected to fall after a launch, with the launch window.

A rocket drops parts as it climbs: boosters, first stages, payload fairings. Before each launch the operator's government defines the sea areas where they are expected to land and asks for them to be broadcast as warnings, with a daily window and backup days in case the launch slips.

Launches from coastal sites in the United States, China, Japan, India, French Guiana and elsewhere account for much of the missile-and-rocket category in this archive. A warning for a launch window says nothing about whether the launch took place in it.

What the archive shows

1,756 messages in this archive use “Rocket launching”, the earliest issued 1999-01-30 and the latest 2026-09-21. None of them is in force in the latest lists we collected. A hazard reported again and again counts once per message.

The largest yearly count is 2023, with 318 messages. Collection is incomplete between 2024-05 and 2026-08-17, so 2024, 2025 and 2026 are not comparable with fully collected years.

Missiles accounts for 1,753 of 1,756 recorded messages (100%), the largest warning type group in this selection.

Located messages that use it fall in 28 sea areas; the most frequent are North Atlantic Ocean (918), Barentsz Sea (162) and North Pacific Ocean (134).

Messages that use it are issued most often in November (179 across all years) and least often in July (114).

By warning series: NAVAREA IV 906, HYDROPAC 384, HYDROARC 258 and NAVAREA XII 103, and 3 more.
