Captain Sarah Martinez still remembers the day she first saw a railgun test fire at the Naval Surface Warfare Center. The thunderous crack echoed across the Chesapeake Bay as a metal slug shot downrange at Mach 7, leaving nothing but superheated air in its wake.
“It was like watching lightning strike in reverse,” she recalls. “You knew you were seeing the future of naval warfare, but nobody could figure out how to make it work on an actual ship.”
That was 2019. Today, as the first Trump class battleships take shape in shipyards across America, that future might finally be arriving.
Why the Navy Is Taking Another Look at Railguns
The Trump class battleships represent the Navy’s boldest surface combat investment in decades. These massive guided-missile battleships pack more firepower than any American warship since World War II, and they’re forcing military planners to reconsider weapons that seemed too futuristic just a few years ago.

General Atomics, the company behind much of America’s railgun research, is now in serious discussions with Pentagon officials about mounting electromagnetic railguns on these new vessels. The timing makes sense – Trump class battleships have the electrical power and deck space that earlier ship designs simply couldn’t provide.
“The power requirements were always the killer,” explains former Navy weapons officer Commander James Walsh. “You need massive amounts of electricity to charge these systems, and older ships just couldn’t handle it without shutting down half their other systems.”
The railgun program officially ended in 2021, victim of budget constraints and technical challenges. But General Atomics kept working on the underlying technology through other projects, and now they’re ready to talk business again.
What Makes These Weapons So Revolutionary
Railguns work by using electromagnetic force to accelerate projectiles to incredible speeds – we’re talking about metal slugs traveling at over 5,000 miles per hour. That’s fast enough to punch through ship armor like tissue paper and hit targets over 100 miles away.
Here’s what sets railguns apart from conventional naval weapons:
- No explosive warheads needed – kinetic energy does all the damage
- Projectiles cost around $25,000 each, versus $1 million for cruise missiles
- Nearly unlimited ammunition capacity (just metal slugs)
- Impossible to intercept due to extreme velocity
- No propellant storage means reduced fire and explosion risks
The Trump class battleships solve railguns’ biggest technical hurdle – power generation. Each ship carries advanced nuclear reactors capable of producing over 100 megawatts of electrical power, more than enough to charge railgun capacitors while maintaining all other ship systems.
| Weapon System | Range (miles) | Cost per Shot | Projectile Speed |
|---|---|---|---|
| Railgun | 100+ | $25,000 | Mach 7+ |
| Tomahawk Missile | 1,000+ | $1.4 million | Mach 0.7 |
| 5-inch Naval Gun | 15 | $1,500 | Mach 2.5 |
“We’re looking at a weapon that bridges the gap between cheap cannon rounds and expensive missiles,” notes defense analyst Rebecca Chen. “For many targets, railguns offer the perfect middle ground.”
Real-World Impact on Naval Warfare
If railguns make it onto Trump class battleships, they could reshape how naval battles are fought. Imagine a weapon that can engage enemy ships, aircraft, and land targets with projectiles that travel too fast for current defense systems to intercept.
The implications extend beyond pure firepower. Railgun-equipped battleships could provide naval gunfire support for Marines landing on hostile beaches, something the Navy hasn’t been able to do effectively since the retirement of Iowa-class battleships in the 1990s.
For taxpayers, railguns represent potential long-term savings. While the initial installation costs run into hundreds of millions per ship, the cheap ammunition could save billions over a vessel’s 30-year service life.
Admiral Patricia Rodriguez, who oversees surface ship development, puts it bluntly: “Every Tomahawk missile we don’t fire is a million dollars back in the treasury. Railguns let us engage more targets for less money.”
The technology also offers strategic advantages. Unlike missiles, which can be jammed or spoofed, railgun projectiles are essentially unstoppable once fired. Enemy radar might detect them, but there’s no defense against a chunk of metal traveling at hypersonic speeds.
Challenges Still Ahead
Don’t expect to see railguns on ships tomorrow. General Atomics and the Navy still face significant technical hurdles, particularly around barrel wear and maintenance. Early railgun prototypes required new barrels after just a few dozen shots.
The company claims they’ve solved most durability issues through advanced materials and barrel cooling systems, but proving these solutions work reliably at sea will take time. Salt spray, rolling decks, and 24/7 operations create challenges that laboratory testing can’t fully replicate.
Budget constraints remain another obstacle. Even with renewed interest from Navy leadership, Congress must approve funding for railgun integration into Trump class battleships. Given the ships’ already substantial cost, adding experimental weapons systems won’t be an easy sell.
“We’re talking about adding a quarter-billion-dollar weapons system to ships that already cost $8 billion each,” acknowledges defense budget expert Dr. Michael Torres. “The math has to make sense from both tactical and financial perspectives.”
What Happens Next
General Atomics expects to know by mid-2024 whether the Navy will move forward with railgun integration. If approved, the first operational railgun could be mounted on a Trump class battleship by 2027.
The decision will likely depend on how well the ships’ other systems perform during sea trials, and whether budget pressures force the Navy to choose between railguns and other advanced weapons like hypersonic missiles.
For now, engineers continue refining the technology while military planners weigh the strategic benefits. Captain Martinez, now overseeing weapons integration for the Trump class program, remains optimistic about railguns’ prospects.
“The physics work, the power systems work, and we finally have ships big enough to carry them,” she says. “Sometimes the future just takes longer to arrive than you expect.”
FAQs
What exactly are Trump class battleships?
They’re the Navy’s newest and largest surface combat ships, designed to carry advanced weapons and provide firepower for major naval operations.
How fast do railgun projectiles travel?
Railgun projectiles can reach speeds over 5,000 mph, or about seven times the speed of sound.
Why did the Navy stop working on railguns in 2021?
The program was halted due to technical challenges and budget constraints, particularly the massive power requirements that existing ships couldn’t meet.
How much does it cost to fire a railgun?
Each railgun projectile costs approximately $25,000, compared to over $1 million for a cruise missile.
When might we see operational railguns on Navy ships?
If approved, the first operational railgun could be deployed on a Trump class battleship by 2027.
Can railgun projectiles be intercepted by defense systems?
Current defense systems cannot effectively intercept railgun projectiles due to their extreme speed and kinetic nature.
