Overview of Witham Field in Stuart, FL

Witham Field, also known as Martin County Airport (ICAO: KSUA), is a public-use general aviation airport serving Stuart, FL, and the surrounding region. Witham Field is a public-use general aviation airport located 1 mile southeast of downtown Stuart in Martin County, Florida, positioned along the St. Lucie River for quick access to waterfront communities, golf courses, and barrier islands.

The airport spans 726 acres and is owned and operated by Martin County. Witham Field does not offer scheduled commercial airline service and focuses on private, corporate, and business aviation needs. The facility serves the general aviation needs of the local community and can accommodate most general aviation aircraft, including smaller business jets.

Jettly frequently arranges private jet and turboprop charters into KSUA for business executives, leisure travelers, and yacht owners visiting the Treasure Coast, drawing from its extensive private charter aircraft network. Locally, the airport is sometimes called “Stuart air” or “Stuart airport,” though its official designation remains Martin County Airport – Witham Field.

Airport History and Role in Martin County

Construction of the airport began in the early 1940s. Originally named MacArthur Field, it was renamed Witham Field in 1942, when the U.S. Navy leased the facility in October 1942. The base served as Naval Auxiliary Air Station Witham, training Navy and Marine Corps aviators from NAS Vero Beach. The airport was named in honor of a local naval aviator, reflecting Stuart’s aviation heritage.

After decommissioning in July 1947, control returned to Martin County. In subsequent decades, Grumman leased significant acreage for manufacturing and flight testing, including work on military aircraft like the OV-1 Mohawk. Today, the airport has evolved into a regional hub for corporate aviation, charters, and flight schools.

The airport’s tenants and flight activities contribute significantly to its revenue streams and overall economic impact on the region. Witham Field’s operations support local businesses and tourism, enhancing the economic landscape of Martin County through jobs in aircraft maintenance, FBOs, and related services.

Runways, Facilities, and Operations at Witham Field

Witham Field features three paved runways and modern general aviation facilities suitable for light aircraft, turboprops, and many business jets. The airport features three runways, which allow for a variety of flight operations and services.

Runway 12/30 is the primary runway at 5,828 feet long and 100 feet wide, surfaced with grooved asphalt in good condition. This runway supports most light, midsize, and some super-midsize business jets under typical operating conditions. The airport is currently installing an engineered materials arresting system (EMAS) on its main runway, Runway 12/30, to enhance safety and prevent overruns. The EMAS system at Witham Field relies on crushable concrete at the departure end of a runway to enhance safety by preventing overruns.

The installation of the EMAS at Witham Field is expected to close Runway 12/30 through October, while Runway 16/34 and Runway 7/25 will remain open during the construction. Runway 16/34 measures 5,000 feet, and Runway 7/25 is 4,653 feet-both accommodate smaller general aviation traffic pattern operations and training flights.

The airfield has instrument approach procedures, medium-intensity runway lighting, and visual glide-slope indicators (PAPI) to support operations under varied weather conditions. An air traffic control tower operates daily between 0700 and 2200 local time at the airport. When the tower is closed, pilots follow standard uncontrolled field procedures.

On-field facilities include hangars, tie-downs, maintenance hangars, and corporate facilities. Multiple flight schools are located on-site, making the airport a regional hub for pilot certifications and training. The airport supports local law enforcement and emergency medical flights to enhance regional safety.

Noise Abatement and Community Considerations

Because Witham Field is close to residential areas in Stuart and Sewall’s Point, Martin County emphasizes strict noise abatement procedures. Aircraft noise has traditionally been a divisive issue at Witham Field, leading to conflicts between airport operators and local residents.

However, Witham Field has worked proactively with community officials and residents to address aircraft noise concerns. A voluntary nighttime curfew and noise abatement program is in effect to minimize noise impact on surrounding residential areas and noise-sensitive areas along the waterfront

Common noise abatement measures include preferred runway use (often runway 12, depending on wind), reduced-power climb profiles, and specific departure routes to avoid dense neighborhoods. The NBAA’s Close-In Departure Procedure has been selected as the optimum noise-abatement departure profile for Witham Field.

Stage 1 and Stage 2 jet operations are strongly discouraged between 2300 and 0800 hours. Touch-and-go operations are limited during certain hours, with specific restrictions noted in airport publications.

Charter customers using Jettly can request operators familiar with KSUA’s local procedures to minimize community impact. This ensures smoother operations and compliance with Martin County’s community-focused approach to airport management.

Nearby Airports Serving Stuart and the Treasure Coast

While Witham Field is the primary Martin County airport for general aviation, several nearby airports can complement travel plans depending on aircraft size, schedule, and route.

Palm Beach International Airport (PBI) in West Palm Beach offers scheduled commercial service and runways long enough to handle larger, heavy jets. However, PBI is farther from Stuart, more congested, and has longer ground-transport times.

St. Lucie County International Airport (KFPR) in Fort Pierce supports general aviation and some commercial traffic but is farther from Stuart and has fewer ground amenities. North Palm Beach County General Aviation Airport (F45) serves lighter general aviation traffic.

Witham Field offers less congestion and closer, more convenient access to Stuart, FL, Jupiter Island, and Hobe Sound. For travelers focused on Martin County or the northern Treasure Coast, KSUA via Jettly often provides faster arrivals and departures. However, very large cabin jets with extended wing span requirements may be better suited to PBI.

Jettly uses its global aircraft inventory and a convenient private jet charter cost estimator to recommend the most suitable airport, Witham Field, or an alternative, based on aircraft performance, declared distances, customs access, and traveler preferences.

Stuart Air Show at Witham Field

The Stuart Air Show is a major annual aviation event hosted at Witham Field. The airport hosts the annual Stuart Air Show every November, featuring military aircraft and aerobatic performances. The 2025 show marked the 36th annual event, with the 2026 edition scheduled for November 13-15.

Practical Tips for Passengers Flying Into Witham Field

For travelers using Witham Field via private charter, particularly first-time visitors to Stuart, FL 34996, a few practical considerations can streamline the experience.

• Ground Transportation: Pre-book car services, arrange ride-share pickups, or reserve rental cars to reach downtown Stuart, Palm City, or coastal communities, or to connect with onward flights such as private jet charters in Atlanta, Georgia. FBOs can assist with arrangements.

• Flight Times: Typical flight times from popular departure cities-Miami (under 1 hour), Orlando (45 minutes), New York (2.5 hours), Atlanta (1.5 hours)-demonstrate how using KSUA shortens door-to-door travel compared with commercial routes through PBI, especially when coordinated with private jet charter services in Houston and other hubs.

• Aircraft Selection: A light jet or turboprop is often sufficient for KSUA. For longer range or larger passenger counts, a midsize jet works well given runway 12’s length. Travelers can also compare shared charter flights vs. full charters when deciding how to fly into Stuart. Consult Jettly’s flight advisors for performance requirements.

• Seasonal Considerations: During the winter months and peak boating season, demand increases and prices tend to rise. Jettly provides guidance on affordable private jet charter, but it is still wise to book early for the best aircraft availability.
