Construction is underway on a
permanent granite helipad on the South Lawn of the White House, marking one of
the most significant changes to the presidential grounds in decades. President
Donald Trump confirmed the project on Monday, saying the new landing pad is
being built specifically to accommodate the Marine Corps’ new VH-92A Patriot
presidential helicopters, whose powerful engines and downward-directed exhaust
have repeatedly damaged the White House lawn.
Photos taken on July 1, 2026, show
crews working around the clock on the circular landing area, replacing a
section of lawn that recently served as the site of a temporary UFC arena. Once
completed, the granite helipad will provide a permanent landing surface for
Marine One while preserving the surrounding landscape from the intense heat
generated by the new aircraft.

The
Marine Corps completed delivery of 23 next-generation Sikorsky VH-92A Patriot
helicopters in August 2024 to replace the aging presidential helicopter fleet.
Although the aircraft offer significant improvements in performance,
reliability, and maintenance costs, they introduced an unexpected problem at
the White House.
Unlike
the older VH-3D Sea King and VH-60N White Hawk helicopters, the VH-92A directs
much of its engine exhaust downward near the rear of the aircraft. Each landing
scorched and tore up portions of the South Lawn, making routine operations
increasingly difficult.
“It
isn’t that the grass gets discolored,” President Trump explained. “It gets
ripped out.”
For
several years, Marines attempted to minimize the damage by placing metal
landing mats on the lawn. Even then, the aircraft’s exhaust often extended
beyond the mat, leaving the surrounding grass badly damaged after each landing.
As a result, the new helicopters saw only limited use at the White House while
the older aircraft remained in regular service.
A Permanent Solution
Rather
than continue repairing the lawn after every landing, the administration
approved construction of a permanent granite helipad.
“It’s
got the seal of the White House on it in carved granite,” Trump said. “It’s
really a beautiful thing.”
According
to the President, Sikorsky Aircraft, a subsidiary of Lockheed Martin, agreed to
pay the entire cost of the project because the company recognized the
operational challenges created by the new helicopters.
“Sikorsky
is paying for it,” Trump told reporters. “They didn’t tell us how powerful
these helicopters were, and they felt a little bit guilty.”
Trump
estimated the project would cost between $5 million and $6 million. However,
construction documents reviewed by The Washington Post indicate the
total cost, including related improvements to the South Portico and surrounding
driveway, could approach $13 million, with an additional $875,000 approved to
accelerate construction.

Construction, the same firm building the new White House ballroom, is
overseeing the project. Work began on June 29 and continues 24 hours a day,
seven days a week, with completion scheduled for September 17, ahead of the
planned September 24 state visit by Chinese President Xi Jinping.
Lockheed
Martin stated that its contribution was made in full compliance with all
applicable laws and regulations through the appropriate federal channels.
Granite
is one of the strongest and most durable natural building materials available,
making it an ideal surface for helicopter operations.
Unlike
grass or gravel, a granite landing pad provides a perfectly level, stable,
dust-free surface capable of supporting heavy aircraft without erosion or
debris being blown into the rotor system. The smooth surface also distributes
landing loads evenly through the helicopter’s landing gear, improving safety
during touchdown.
A
former Marine One pilot noted that a level landing surface allows equal
compression of the landing struts, reducing stress on the aircraft and
providing a safer landing environment.
The
completed helipad will also feature the official White House seal carved
directly into the granite and may occasionally serve as a platform for outdoor
press conferences and ceremonial events.
Many
White House observers have long questioned why the Executive Mansion never had
a permanent presidential helipad. For decades, Presidents and First Ladies have
walked across the often wet South Lawn in dress shoes and heels before boarding
Marine One.
The
White House lawn itself also slopes gently away from the South Portico, making
helicopter landings more challenging than on a purpose-built landing surface.
Interestingly,
President Richard Nixon’s Florida compound at Key Biscayne featured a dedicated
helicopter landing pad constructed adjacent to Biscayne Bay, providing a level
and permanent landing area during his frequent visits.
The
new White House helipad follows that same principle by creating a safer and
more efficient operating environment for presidential helicopter operations
The End of an Era
The Marine One mission has relied primarily on Sikorsky VH-3D Sea King helicopters since 1978, with VH-60N White Hawks joining the fleet in the late 1980s. Multiple efforts to replace the aging helicopters began during the George W. Bush administration but were canceled because of rising costs. The modernization effort resumed under President Barack Obama, ultimately leading to the 2014 contract awarded to Sikorsky for development of the VH-92A Patriot.

The
new granite helipad finally removes that obstacle, allowing the Marine Corps to
transition fully to the VH-92A fleet while retiring helicopters that, in some
cases, have served Presidents for nearly half a century.
The Engineering Behind the VH-92A
The
VH-92A Patriot represents the most technologically advanced presidential
helicopter ever built. Developed by Sikorsky, a Lockheed Martin company, it is
based on the proven civilian S-92 medium-lift helicopter but extensively
modified for the unique demands of presidential transport.
In
addition to a hardened communications suite, defensive countermeasures,
electromagnetic shielding, executive interior, and enhanced navigation systems,
the aircraft is designed to serve as an airborne command post capable of
supporting the President during national emergencies. Powered by two General
Electric CT7-8A6 turboshaft engines, the VH-92A has a maximum gross weight of
approximately 27,700 pounds and can carry a crew of four along with up to 14
passengers.

Every helicopter remains airborne by forcing a large
column of air downward. This moving column of air, known as rotor downwash,
creates the lift needed to support the aircraft’s weight.
The heavier the helicopter and the more power applied
by its engines, the greater the volume and velocity of this downwash. During
landing, especially in confined areas such as the White House South Lawn, the
rotor system creates a concentrated stream of high-energy air that strikes the
ground before spreading rapidly in all directions.
This airflow is strong enough to lift loose debris,
move gravel, scatter landscaping materials, and flatten vegetation. On grass
surfaces, the combination of aerodynamic force and engine heat can remove
moisture from the soil, damage root systems, and literally tear the turf from
the ground. The effect is even more pronounced when a helicopter hovers for
several seconds before touchdown or after liftoff.
Why the VH-92A Damages the White House
Lawn
The principal issue is not simply
rotor downwash, but the interaction between the rotor wash and the helicopter’s
exhaust system.
The older VH-3D Sea King, which
entered presidential service in the 1970s, routes much of its engine exhaust
outward and away from the ground. While the aircraft still generates
substantial downwash, relatively little extremely hot exhaust is driven directly
into the landing surface.
The VH-92A, however, is derived
from the commercial S-92, whose engine installation places the exhaust outlets
farther aft and closer to the rotor system. During hover, the main rotor forces
the hot exhaust plume downward where it mixes with the rotor downwash before
striking the ground. The result is a concentrated blast of high-temperature air
capable of scorching grass almost immediately under certain wind and
atmospheric conditions. This issue became significant enough that landing-zone
suitability for grass surfaces was identified as one of the program’s remaining
technical challenges, prompting engineering modifications to the rotor system
intended to reduce heat damage while the rotors are turning.
Landing Loads and Why a Level Surface
Matters
Another advantage of a permanent
helipad is structural rather than aerodynamic.
When a helicopter touches down, its
landing gear and shock struts are designed to absorb the aircraft’s weight
evenly. If the landing surface is uneven or sloped, one landing gear may
compress before the others, increasing structural loads on the airframe and
rotor mast.
The White House South Lawn has a
noticeable slope away from the South Portico. While experienced Marine One
pilots have operated safely there for decades, a perfectly level granite
landing surface distributes landing loads more uniformly through all three
landing gear, reduces side loading on the struts, and minimizes stress on the
aircraft during repeated operations.
A former Marine One pilot has noted
that equal compression of the landing gear improves stability during touchdown
and provides the safest possible landing environment for both crew and
passengers.
Granite
offers several operational advantages over grass. It provides a rigid, level
surface that will not rut, settle, or erode under repeated helicopter
operations. Unlike gravel or asphalt, properly finished granite produces
virtually no loose debris that could become dangerous foreign object damage
(FOD) when caught in rotor wash. The stone also tolerates repeated exposure to
hot exhaust without deterioration and requires far less maintenance than
constantly repairing sections of damaged turf. Because the landing area remains
dimensionally stable over time, pilots also benefit from a consistent visual
reference during every approach.
For
these reasons, permanent helicopter landing facilities at military
installations, hospitals, offshore platforms, and executive transport
facilities are almost always constructed from reinforced concrete or stone
rather than maintained turf.
In
many respects, the White House granite helipad brings presidential helicopter
operations in Washington into line with long-established aviation engineering
practices. Rather than serving as a cosmetic improvement, it addresses
aerodynamic, structural, and operational issues that have become increasingly
apparent with the introduction of the more capable VH-92A Patriot.
