TROJAN SPIRIT

TROJAN SPIRIT is a communications system operated by U.S. military intelligence, which is approved for handling information of the highest security levels. While the compartmented control system information it handles is principally for intelligence (i.e., TOP SECRET sensitive compartmented intelligence (TS/SCI), it can also be used for the most sensitive command and operations information, at the collateral TOP SECRET level and above.

It is a tactical network that allows sharing of this information among appropriate elements in the field, but also provides connectivity to worldwide maximum security networks such as JWICS and specific United States intelligence community networks. While it is tactically used, however, there is a TROJAN Data Network (TDN) operations center at Ft. Belvoir, VA.

Its implementation is evolving as part of the restructuring of the United States Army. Within a division, before the full change to Brigade Combat Teams BCT, there are 17 points that need TS/SCI access. It is expected there will be three such points per BCT.

Implementation

TROJAN SPIRIT direct and JNN connectivity

Originally, each TROJAN SPIRIT node had its own AN/TSQ-190(V) satellite terminal; TROJAN SPIRIT had often been considered synonymous with the combination of satellite and ground communications & security equipment.With the availability of the Joint Network Node, there would still be a satellite terminal per BCT, but other users in "TS/SCI enclaves" would reach it using secure tunneling through the Joint Network Node. TS/SCI communications require KG-175 tactical fastlane (TACLANE) in-line network encryption (INE) devices. These points of access are called WIN intelligence gateways (WIN-IG).

TROJAN SPIRIT II is being replaced by the AN/TSQ-226(V)TROJAN SPIRIT LITE. The TROJAN SPIRIT LITE is fielded in four versions, admittedly with the question if 22 cases in V(1), some of which require 4 men to lift, are in fact "lite"::

• (V)1 -a commercial off-the-shelf version in a transit case configuration used to augment Military Intelligence dissemination and communications requirements primarily at corps and division, and some EAC
• (V)2 for the Marines
• (V)2-SBCT (pallet, shelter, ECV, trailer) for Army Brigade Combat Teams
• (V)3 is similar to (V)2 but adds an additional shelter and workstation.
• (V)4 for Echelons above Corps

Deployment

TROJAN SPIRIT was used extensively in Operation DESERT STORM and subsequent operations. In addition to its use with national intelligence systems, it also was used for communications among U.S. Army PROPHET tactical electronic intelligence systems, as well as U.S. Marine Corps field headquarters.

Evolution

TROJAN SPIRIT internally migrated from Asychronous Transfer Mode to Internet Protocol version 4 communications with TROJAN SPIRIT II. To evolve the TROJAN SPIRIT II, the satellite communications had to be upgraded, with more efficient radio modems and TSEC/KIV-19 cryptographic equipment to supplement slower TSEC/KIV-7HS units. These upgrades were selected before the BCT restructuring of the Army, so concentrate on requirements at division, corps, and echelons above corps.

The next step is to integrate TROJAN SPIRIT II with common networks. TROJAN SPIRIT already goes through JNN, and JNN is compatible with Warfighter Information Network-Tactical.
