Secure navy messaging, from ship to shore and across the fleet.
Troop Messenger is a secure navy messaging application for ship-to-shore, ship-to-ship and shore-based communication. It runs on the navy’s own servers or a fully air-gapped network and is built for the narrow, high-latency satellite links that connect ships at sea.

What Is a Navy Messaging Application?
A navy messaging application is a secure messaging, calling and file-sharing platform that a navy hosts itself, built to work over the narrow and intermittent satellite links that connect ships at sea with shore commands.
It sits on top of the naval communication systems a fleet already runs, satellite, line-of-sight and shore networks, and carries the everyday text, images and files that signal traffic was never designed for.
| Used by | Fleets, ships, shore establishments, dockyards, maritime operations centres and coast guards |
|---|---|
| Links | Satellite, line-of-sight and shore networks, optimised for high latency |
| Out of contact | Messages queue and deliver in order when the link returns |
| Deployment | Shore servers, shipboard servers or fully air-gapped |
| Coalition | Orange Member guest access for partner navies |
| Encryption | End-to-end: ECDH SECP384R1, PBKDF2, AES-256 |

Why Naval Communication Needs Its Own Messaging
Bandwidth at sea is scarce.
Satellite links are narrow, shared and expensive, so every message has to count.
Ships go out of contact.
Emission control, weather and coverage gaps cut links for hours, and messages must not be lost.
Fleets work with other nations.
Task groups, exercises and port visits bring partner navies into conversations, but not into your network.
Crews fall back on personal apps.
In port and ashore, official matters slip onto consumer apps outside your control.

FAQ
Frequently Asked Questions
A navy messaging application is a secure messaging, calling and file-sharing platform that a navy hosts itself, built for the narrow, intermittent satellite links between ships and shore. Troop Messenger runs on the navy’s own servers or fully air-gapped networks.
Troop Messenger runs on servers ashore and ships connect over their existing satellite links. It is optimised for high latency, using network accelerators to reduce round-trip time, jitter and packet loss, so messages and files get through on narrow links.
Messages are held and delivered in order when the link returns, so nothing is lost during emission control or coverage gaps. [Confirm queue behaviour before publishing]
Submarines can use it whenever they have a data connection, for example alongside in port or over satellite when communications allow. It does not replace specialist submarine communication systems.
Yes. Orange Member gives partner navies, liaison officers and dockyard contractors guest access to named groups only, without an account on your network. Administrators can remove them at any time.
Yes. Coast guards use the same platform to connect shore stations, vessels and aircraft for search and rescue, patrols and maritime security, on their own servers or air-gapped networks.
Yes. Messages, call records, files, keys and logs stay on servers the navy owns. There is no foreign cloud and no third-party processor.
Start with a security briefing with our solutions architect, then run a pilot ashore or on an isolated test network that mirrors your ship-to-shore links.
