What Telephonics Corporation does

Telephonics Corporation is a U.S.-based aerospace and defense electronics company founded in 1933 and headquartered in Farmingdale, New York, with engineering facilities in Huntington, NY and Huntsville, AL and a regional office in Hong Kong. The company operates as a wholly-owned subsidiary of TTM Technologies (NYSE: TTMI) following TTM's $330 million acquisition completed on June 27, 2022, and constitutes a majority of TTM's aerospace and defense segment, which represents approximately 46% of TTM's fiscal 2025 revenue.

Telephonics designs, develops and manufactures advanced surveillance, communications, identification, and integrated sensor systems for land, sea and air defense and civil aviation applications. Core product lines include MOSAIC dual-beam AESA radar, APS-143 OceanEye and AN/APS maritime surveillance radars for anti-submarine warfare, the AN/UPX family of AIMS-certified Mode 5 IFF interrogators, the NSA Type 1 certified TruLink wireless intercom system, AeroTrac air traffic management automation, Mobile Surveillance Capability (MSC) border security systems, and custom analog/mixed-signal integrated circuits (TLSI). Differentiated technical features include dual-beam simultaneous SAR/ISAR and GMTI/MMTI from a single aperture, Mode 5 AIMS-certified IFF, and FIPS 140-2 / NSA Type 1 certified encryption.

The business model is anchored on direct enterprise field sales to defense and government customers via long-cycle procurement contracts (IDIQ, firm fixed price). Customers include the U.S. Navy, U.S. Air Force, U.S. Marine Corps, U.S. Army, U.S. Customs and Border Protection, allied defense ministries (Indian Navy, Swedish FMV, Israel, Republic of Korea), civil aviation authorities (China CAAC), and defense primes including Boeing, Northrop Grumman and SAAB. Revenue is generated through hardware sales of integrated subsystems and through technical and product support services (MRO, training, technical field support, parts) delivered via an authorized repair facility network. Pricing is quote-based and contractually determined; Telephonics does not publicly disclose product pricing, and individual revenue is not separately reported by TTM.

Direct peers

• L3Harris Technologies: L3Harris is a direct peer across multiple Telephonics lines: IFF interrogators, secure wireless intercoms, airborne and maritime surveillance radar, and electronic warfare subsystems for US DoD and allies. Both companies sell certified defense electronics subsystems integrated onto Boeing, Northrop and Lockheed platforms, competing head-to-head on Mode 5 IFF and tactical comms bids.
• Hensoldt: Hensoldt is one of the closest pure-play peers: a specialist in identification (IFF), radar, and electronic warfare serving European and allied militaries. It directly competes with Telephonics on transatlantic IFF and surveillance radar bids (e.g., for German, Spanish, and broader NATO procurement) and is a benchmark for specialized defense-electronics valuation.
• Saab: Saab is a direct peer in maritime and ground-based surveillance radar, IFF, defense communications, and ATM automation, and is explicitly a Telephonics platform-integration partner on the RDR-1700B. It competes head-to-head on European and US-aligned naval and littoral radar opportunities.
• Leonardo DRS: Leonardo DRS is a closely comparable defense electronics integrator with strengths in IFF, advanced sensing and integrated communications for naval and airborne platforms, and a similar dual-market US/Italy footprint. It competes directly with Telephonics on shipboard and airborne IFF and sensor subsystems and shares a Tier-2 supplier role to US primes.

Regional players

• Indra Sistemas: Indra is a comparable peer in air traffic management automation, surveillance radar, and defense electronics serving primarily European (especially Spanish) and Latin American customers. It competes with Telephonics' AeroTrac line in similar international ATM bids and shares a focus on secondary radar/ADS-B ground infrastructure.

Emerging players

• Terma: Terma is a European specialist in radar, IFF-related sensors, EW and aerospace electronics for US-aligned platforms (F-35, F-16, Patriot, naval platforms). It overlaps with Telephonics on airborne self-protection and platform-integration subsystems and competes in Nordic, US and other allied markets.

Broad incumbents

• BAE Systems Electronic Systems: BAE Systems Electronic Systems is a broad incumbent across IFF, EW, sensors and secure communications for US and allied forces. It offers overlapping products to Telephonics' portfolio and competes on US Navy and allied platform opportunities while supplying Tier-1 primes.
• Thales: Thales is a broad incumbent defense electronics prime covering IFF (TSA-1600/1700 series), air surveillance radar, secure communications, and ATM, overlapping directly with Telephonics' four core product lines. It competes on international IFF and ATC opportunities where Telephonics also bids, particularly in Europe, Middle East, and Asia-Pacific.
• RTX (Raytheon): Raytheon (now RTX) is a broad incumbent across radar (APY-10 family that co-flies with Telephonics' APS-143 on P-8I), IFF and integrated mission systems. It directly competes with Telephonics on airborne maritime radar and air-defense IFF opportunities for the US Navy and allied forces.
• Northrop Grumman Mission Systems: Northrop Grumman is both a Telephonics integration partner (G/ATOR, MQ-8B Fire Scout) and a competitive incumbent on integrated air-surveillance, radar and IFF system-level opportunities. It bundles radar, IFF and C2 into platform-level offerings that compete with Telephonics' standalone subsystems.
