1. SCOPE

1.1 SYSTEM IDENTIFICATION. The existing Man-Portable (MP) Tactical Air Navigation (TACAN) system for the United States Air Force (USAF) is the AN/TRN-41. The USAF is replacing it the AN/TRN 41. This document will support this acquisition effort known as the MP TACAN Replacement.

1.2 SYSTEM OVERVIEW. The AN/TRN-41 is a ground-based system that provides a TACAN signal which can be used by any aircraft with a TACAN receiver to help navigate. The AN/TRN- 41 is small and easily transportable versus the various fixed-base systems found at many airports around the world. The existing AN/TRN-41 was fielded back in the 1970s so is maintenance- intensive with insufficient quantities available to meet mission needs, resulting in a requirements gap.

1.3 DOCUMENT OVERVIEW. This System Requirements Document (SRD) provides performance requirements for procuring a replacement for the existing AN/TRN-41 MP TACAN.

1.4 REQUIREMENTS ORIGIN. Headquarters Air Force Flights Standards Agency (HQ AFFSA) provided a Replacement of MP TACAN Requirements Memorandum dated 16 December 2020 from which this document is based. In addition, AFFSA provided a document entitled HQ AFFSA MP- TACAN System Requirements Memorandum Change, dated 3 Nov 2021, which documents changes to requirements. The requirement document was reviewed to ensure its applicability and accuracy. This SRD version contains the current Air Force requirements to support procurement of the AN/TRN-41 MP TACAN Replacement system.

2. APPLICABLE DOCUMENTS
