L3Harris Technologies
L3Harris Technologies, Inc. is a major U.S. defense-technology and aerospace company headquartered in Melbourne, Florida. The company supplies mission-critical systems to the U.S. government, allied governments, military organizations, civil agencies, and commercial customers. Its technologies support operations across space, air, land, sea, and cyber domains, including communications, electronic warfare, missile systems, satellites, sensors, propulsion, avionics, mission systems, and defense electronics.
The modern L3Harris organization was formed in 2019 through the merger of Harris Corporation and L3 Technologies. Since then, it has continued to reshape its portfolio through acquisitions, divestitures, internal investment, and the addition of Aerojet Rocketdyne. L3Harris reported approximately $21.9 billion in 2025 revenue and had approximately 45,000 employees as of January 2, 2026, including around 18,000 engineers and scientists.
L3Harris made another important structural change in January 2026 by reorganizing from four operating segments into three: Space & Mission Systems, Communications & Spectrum Dominance, and Missile Solutions. An additional major leadership update followed on August 17, 2026, when Sam Mehta became President and Chief Executive Officer, replacing Christopher Kubasik, while Lewis Hay III became Independent Chairman.

Shareholders should contact Investor Relations at 321-724-3170 or InvestorRelations@L3Harris.com, while registered-shareholder account issues should go to Computershare at 1-888-261-6777. Media inquiries should use 321-306-8927 or Media@L3Harris.com.

Complaints may involve a supplier relationship, contract matter, shareholder issue, recruitment concern, ethics matter, employment interaction, product-support problem, or another corporate issue. Before escalating, collect purchase orders, contract numbers, program information, names of employees involved, correspondence, invoices, transaction records, and any existing case references.
Begin with the L3Harris facility, program office, contract representative, product-support team, or business segment responsible for the issue. Because L3Harris does not maintain a universal consumer call center, using the correct operational contact is essential. If necessary, call corporate headquarters at 321-727-9100 and request routing.
Supplier complaints should go through supply-chain or procurement contacts, shareholder matters through Investor Relations or Computershare, job-application matters through the careers system, and media issues through Corporate Public Relations. Using the department directly responsible for the relationship can greatly shorten the escalation process.
If the first contact cannot resolve the complaint, request escalation to a program manager, contract manager, business-unit leader, procurement supervisor, HR representative, or another appropriate manager. Provide a concise written chronology and relevant supporting documents.
For serious corporate concerns, submit the issue in writing to the responsible L3Harris department or corporate office. Written correspondence should identify the relationship with L3Harris, dates, previous contacts, documents, and the exact resolution being requested.
Unresolved corporate correspondence can be sent to L3Harris Technologies, Inc., 1025 West NASA Boulevard, Melbourne, FL 32919. This is the company’s current principal corporate address.
Ethics, compliance, supplier-standard, securities, or employment concerns should use the applicable specialized channel. L3Harris specifically encourages suppliers who believe they are being pressured to violate laws or company standards to contact its Business Standards Office.
The correct regulator depends on the complaint. Securities issues may involve the SEC, government-contract matters may involve the responsible agency or inspector general, labor concerns may involve employment regulators, and export-control or procurement matters can fall under other specialized federal authorities.
L3Harris is not primarily a consumer business, so ordinary consumer-protection routes are less common. However, shareholders, vendors, employees, and commercial counterparties may have contractual, securities, payment, or administrative remedies depending on the type of dispute.
For unresolved contractual, employment, supplier, securities, or commercial matters, review the controlling contract, purchase order, employment agreement, or other legal documents. Formal notice, mediation, arbitration, administrative proceedings, or litigation may be appropriate depending on the governing terms and applicable law.
