Blimps serve a surprisingly wide range of purposes, from advertising and live sports coverage to military surveillance, scientific research, and experimental cargo transport. While they’re no longer a mainstream mode of travel, these lighter-than-air aircraft remain uniquely suited to jobs that require slow, stable flight over a fixed area for extended periods.
Advertising and Brand Promotion
The most familiar use of blimps is airborne advertising. Goodyear launched its first blimp, the Pilgrim, in 1925, and a century later the company still operates three airship bases in the United States (in Carson, California; Pompano Beach, Florida; and Akron, Ohio). In 2025, the Goodyear Blimp is scheduled to visit more than 100 cities across North America and Europe, appearing at major sporting events, music festivals, and cultural gatherings. The sheer size of a blimp, combined with its ability to hover slowly over crowds, makes it a moving billboard that’s almost impossible to ignore. Despite being seen by millions from the ground each year, only about 0.0006% of Americans have actually flown inside one.
Other companies and brands have used blimps for similar purposes, though Goodyear remains the most recognizable. The economics are straightforward: a blimp floating above a packed stadium or concert venue guarantees camera time and social media attention at a fraction of the cost per impression of traditional advertising.
Live Sports Broadcasting
If you’ve watched a football game, golf tournament, or NASCAR race on television, you’ve almost certainly seen aerial footage shot from a blimp. These aircraft carry specialized camera systems that provide sweeping overhead views of stadiums, courses, and racetracks. The technology has kept pace with broadcast standards. CBS Sports and aerial camera operator Winged Vision, for example, upgraded the Goodyear Blimp’s camera rig to a 4K HDR system featuring a Sony HDC-P50 camera, a Canon 45-to-1 zoom lens, and a gyro-stabilized gimbal that keeps the image rock-steady despite wind and movement.
Blimps are better suited to this job than helicopters or drones for a simple reason: they can loiter quietly over an event for hours without refueling, producing minimal noise and vibration. The camera systems are designed to be lightweight and power-efficient since every pound and watt matters on an aircraft that relies on buoyancy rather than engine thrust.
Military and Border Surveillance
Tethered blimps, often called aerostats, are a workhorse of military and border security operations. U.S. Customs and Border Protection operates a network of aerostats along the southern border, each carrying a radar unit weighing about 2,200 pounds that can detect aircraft up to 200 miles away. Wireless transmitters relay radar data into a shared network, giving agents a wide-area picture of air traffic in real time.
Smaller aerostats operate at altitudes between 500 and 5,000 feet and carry a different sensor package: radar, infrared cameras, and high-resolution electro-optical cameras. These deliver live imagery directly to Border Patrol agents on the ground, allowing them to track movement across remote terrain around the clock. The larger systems carry enough fuel for four continuous days of operation, making them far cheaper to keep aloft than manned aircraft or drones that need to land and refuel every few hours.
The military also uses aerostats for base protection in conflict zones. Several models exist for different missions, ranging from rapid-deployment systems small enough to set up quickly in the field to persistent surveillance platforms designed to stay airborne for days at a time.
Atmospheric and Environmental Research
Blimps and airships offer something no other aircraft can match for atmospheric scientists: the ability to fly low and slow through a column of air, sampling conditions at precise altitudes. A 2022 study published in Atmospheric Measurement Techniques described a series of research flights aboard a Zeppelin in Germany that measured ten trace gases simultaneously, including carbon dioxide, methane, nitrous oxide, ozone, sulfur dioxide, and ammonia. The instrument, a quantum cascade laser spectrometer, recorded data once per second with high precision.
Alongside the gas analyzer, the research flights carried electrochemical sensors for additional pollutants, optical particle counters to measure airborne particulate matter, and GPS-equipped sensors tracking temperature, humidity, and altitude. This combination lets scientists build a detailed vertical profile of air quality within the lowest layer of the atmosphere, the zone where pollution from traffic, industry, and agriculture concentrates. Fixed monitoring stations on the ground can only sample air at one height. A blimp can rise and descend through that same air column repeatedly, capturing how pollutant concentrations change with altitude and time of day.
Heavy Cargo Transport
One of the most ambitious proposed uses for blimps is hauling oversized cargo to locations that lack roads, rail lines, or deep-water ports. Mining operations in northern Canada, oil infrastructure in remote Arctic regions, and wind turbine components destined for mountaintop sites all present the same logistical problem: the cargo is too heavy or too large for helicopters and too remote for trucks. Several companies have worked on heavy-lift airship designs to fill this gap. Germany’s CargoLifter AG designed the CL160, a massive airship with a 160-ton payload capacity, roughly equivalent to lifting three fully loaded semi-trucks at once. Some conceptual designs have pushed projected payloads even higher, up to 600 tons.
None of these super-heavy cargo airships have reached commercial operation yet, and the engineering challenges are significant. But smaller hybrid airships that combine buoyancy with aerodynamic lift are in active development, targeting payloads in the 10- to 50-ton range for deliveries to roadless communities and industrial sites.
High-Altitude Communications and Observation
At the other end of the altitude spectrum, unmanned stratospheric airships are designed to operate at around 20 to 21 kilometers (roughly 65,000 feet), well above commercial airline traffic and weather systems. At that height, wind speeds are low and the thin air requires very little energy to maintain position. The concept dates back to a U.S. Navy program in 1972, and modern versions aim for extraordinarily long endurance, with some designs targeting five years of continuous unmanned flight.
These high-altitude platforms could serve as alternatives to satellites for telecommunications relay, internet coverage over rural areas, and persistent Earth observation. They’re far cheaper to launch and maintain than an orbiting satellite, and because they hover over a fixed point rather than orbiting the planet, they provide continuous coverage of a specific region. While still largely in the development and testing phase, stratospheric airships represent one of the most active areas of lighter-than-air engineering today.
Why Blimps Use Helium
Modern blimps are filled with helium, a non-flammable gas that provides about 93% of the lifting force of hydrogen without the catastrophic fire risk. Aviation regulations in the U.S. and Canada explicitly require non-flammable lifting gas in airships. Canada’s aviation rules go further, stating outright that hydrogen is not acceptable. These regulations exist largely because of the 1937 Hindenburg disaster, which effectively ended the era of hydrogen-filled passenger airships. Helium is more expensive and occasionally subject to supply shortages, but the safety margin is non-negotiable for any crewed or urban operation.
