L3Harris Headquarters in Melbourne, Florida

The L3Harris Technologies headquarters is at 1025 West NASA Boulevard, Melbourne, Florida 32919, the address the company gives as its principal executive offices.

That address and the main telephone number, (321) 727-9100, appear on the cover of the company's Form 10-K for fiscal 2025, dated February 12, 2026 (L3Harris 10-K). The company website gives the identical location, 1025 W. NASA Boulevard in ZIP code 32919, as its Corporate Headquarters (L3Harris). The campus is a corporate office, not a visitor attraction, and no public tour program is listed on either page.

The headquarters is only one piece of the company's Brevard County footprint. As of January 2, 2026, the 10-K lists major operations of the space and airborne business in Palm Bay, Melbourne and Malabar, and of the communication business in Melbourne and Sunrise, Florida (L3Harris 10-K). When the merger closed in 2019, two of the four new segments, Integrated Mission Systems and Space and Airborne Systems, were headquartered in Palm Bay rather than Melbourne (2019 merger release).

The company itself flags one local risk to the site. Its 10-K warns that the corporate headquarters and significant business operations are located in Florida, which is subject to the risk of major hurricanes (L3Harris 10-K).

L3Harris traces its Melbourne headquarters to Harris Corporation, which merged with Radiation, Inc. in 1967 and established its head office in Florida in 1978; when Harris merged with L3 Technologies in 2019, the combined company was announced as headquartered in Melbourne.

A Harris overview filed with the SEC in November 2018 puts 1895 as the company's founding year and lists the 1967 merger with Radiation, Inc. on its history timeline (Harris 2018 overview). In December 2024 the company described itself as headquartered in Florida since 1978 and as the largest aerospace and defense company in the state, in a release where the Florida Secretary of Commerce welcomed its growing presence on the Space Coast (L3Harris).

The all stock merger of Harris Corporation and L3 Technologies closed on June 29, 2019. The completion release, datelined Melbourne on July 1, 2019, said the combined company was headquartered in Melbourne, Florida, ranked as the sixth largest defense company in the U.S., and had about $17 billion in revenue and 50,000 employees (L3Harris 2019 release). Harris stock, which had traded as HRS, began trading as LHX on July 1, 2019.

Company releases still carry a Melbourne dateline. On August 17, 2026, a release from Melbourne said the board had appointed a new president and chief executive officer and named an independent chairman, effective immediately (L3Harris August 2026 release). The release names no change of headquarters, and the company site still lists its Corporate Headquarters on W. NASA Boulevard (L3Harris about page).

The City of Melbourne counted 1,778 L3Harris employees inside the city in fiscal 2025, the fifth largest employer and 4.29 percent of city employment, down from 2,532 and third place in 2016.

The counts come from the principal employers schedule in the city ACFR covering the fiscal year to September 30, 2025, which compares the current year with nine years earlier and draws on the city Revenue Department and the companies listed (City of Melbourne ACFR 2025).

The city schedule states each employer as a share of total city employment, so it is a Melbourne count rather than a Brevard County one. L3Harris reported 9,000 employees at 27 locations across Florida in December 2024, a company figure that includes its Palm Bay and Malabar sites (L3Harris). Company wide it had about 45,000 employees on January 2, 2026, including about 18,000 engineers and scientists, with 90 percent in the U.S. (L3Harris 10-K). No official source read for this page splits the company's Brevard headcount by city, so the fall from 2,532 to 1,778 in the Melbourne schedule cannot be read as a county wide loss.

On the 2025 tax roll L3Harris Technologies ranked seventh among Melbourne property owners, holding $43,901,730 of taxable assessed value, or 0.49 percent of the city total.

The principal property taxpayers schedule in the city's 2025 financial report, sourced to the Brevard County Property Appraiser, shows the company at fourth place in 2016 with $26,185,000, or 0.68 percent (City of Melbourne ACFR 2025). Its taxable value rose by about two thirds over nine years while its share fell, because the city's tax base grew faster. The Melbourne Airport Authority tops the 2025 list at $199,534,446, and six owners in all rank above L3Harris.

The utility schedules tell a similar story. In 2016 L3Harris was the seventh largest water customer of the city system, at $88,266, and the fifth largest sewer customer, at $130,971; neither L3Harris row appears in the 2025 top ten, where the City of West Melbourne is the largest water customer and Holmes Regional Medical Center, Florida Institute of Technology and Northrop Grumman lead the sewer list (City of Melbourne ACFR 2025). Each L3Harris line in those schedules carries a footnote recording the June 29, 2019 merger of Harris Corporation and L3.

L3Harris is a defense contractor that reported $21,865 million in revenue for fiscal 2025 and has reported in three segments since the start of fiscal 2026: Space and Mission Systems, Communication and Spectrum Dominance, and Missile Solutions.

Revenue rose from $21,325 million in fiscal 2024, and the company ended 2025 with a contractual backlog of $38.7 billion, 13 percent above the prior year (L3Harris 10-K). Beginning fiscal 2026 it cut its reporting segments from four to three. The 10-K says the space segment combines satellite and payload work, including missile warning and defense, the communication segment joins resilient communications and electronic warfare, and Missile Solutions unites propulsion, hypersonics and other missile technologies.

The company's own site sums up the current shape as $21.9B+ in annual revenue, 100+ countries and 3 strategic segments (L3Harris). Those are company statements; the audited figures are in the 10-K. For Melbourne, the practical link is that the communication and space businesses both list Melbourne among their major operating sites in the January 2026 filing.

The incentive on record is a $2 million state High Impact Business Performance (HIPI) grant that L3Harris announced in December 2024 for two new buildings in neighboring Palm Bay, not for the Melbourne headquarters.

The company says the grant pays $1 million in 2025 and $1 million in 2027. The first, a building of about 93,000 square feet for satellite integration, was projected to bring roughly 100 new jobs paying an average of about $105,000 a year; the second, a microelectronics plant of roughly 98,000 square feet, was to bring about 100 jobs at an average near $111,000 (L3Harris December 2024 release). These are the company's own projections.

The program rules are in state law. Section 288.108, Florida Statutes, defines an eligible business as one in a designated high impact sector making a cumulative investment of at least $50 million and creating at least 50 new full time equivalent jobs, and requires that 50 percent of the grant be paid once the business certifies operations have commenced (Florida Statutes 288.108). The City of Melbourne's incentives summary describes the same tool as a negotiated grant used to attract and grow major high impact facilities in Florida (City of Melbourne).
