Navy Making Room for Railguns in Next Warship, But No Extra Investments
By: Megan Eckstein
THE PENTAGON – The Navy's next large surface combatant will have all the space, weight and power margins the sea service could need now and into the future to accommodate new weapons in development – but the director of surface warfare said the Navy would not accelerate weapons development to get them ready in time to outfit the new ships.
Rear Adm. Ron Boxall, OPNAV N96, spoke to USNI News on Aug. 28, in his first interview on the Future Surface Combatant program since its initial capabilities document was signed out by leadership.
Noting that the next large surface combatant would pull from some of the advances made with the Zumwalt-class destroyers (DDG-1000) – including potentially its integrated power system that could easily support laser guns, an electromagnetic railgun, powerful radars and other power-hungry technologies – Boxall told USNI News that the new large surface combatant represented an opportunity to put these technologies into the surface fleet whereas the legacy Arleigh Burke-class destroyers simply do not have the power and cooling capacity to do so.
“We're just excited that we think we do have something that is expandable, has SWaP-C (space, weight, power and cooling) for the future. I think all of us were kind of a little bit nervous about the DDG Flight III and whether we'll have long-term ability to put future energy weapons on there, or the power that we need for directed energy, lasers, things like that,” he said.
But just because the new ship will be able to support energy weapons doesn't mean Boxall wants to accelerate energy weapons development to ensure they're ready to field on the first new ships. He said moving to the Future Surface Combatant in 2023 is an “aggressive timeline” and that at some point the Navy will have to “snap the chalk line and say, this is what you have that's good enough to go on there” – and if a technology isn't ready, it would wait for fielding in a later block buy of the ship.
With the Navy already seeking a new hull to better support the Aegis Combat System and the AN/SPY-6(V) Air and Missile Defense radar – collectively called the DDG-51 Flight III capability – Boxall said he didn't want to force too many changes all at once.
“So I'm inclined to say, as long as we build it modularly, we're going to make those assessments in stride” in terms of inserting in new weapons as they come through the development process, he said.
“But I don't want to get too crazy about trying to accelerate new technology in the first of the class as we change hulls, which will hopefully be a hull that will be with us for a very long time.”

Israeli firm sells Harop, Rotem kamikaze drones to several Asian countries
By: Seth J. Frantzman JERUSALEM — Israel Aerospace Industries on Monday announced more than $100 million in contracts for loitering munitions in three deals that include the Rotem VTOL and the Harop drones. The latter was sold in its land and naval versions. In keeping with the usual policy in Israel, the company did not reveal its customers, only saying that a foreign country acquired Rotem, while the naval and ground versions of Harop were sold in Asia. IAI said the contracts are proof of the importance that modern armies place in having accurate munitions, noting the deals may serve as a “harbinger of additional business activity.” Loitering munitions are sometimes referred to as kamikaze drones because they can be used as a weapon by crashing into a target. These weapons can also hunt down enemy air defenses, among other critical targets. The Harop maritime variant provides an operational solution for a range of vessels, IAI said. “In a complex naval theater, the Harop system gives mission commanders in a fleet of ships the capability to independently and organically collect intelligence, assess targets and strike,” the firm has said. It can also be used as an alternative to or complement sea-to-sea missiles, and is useful in both low- and high-intensity conflict as well as counterterror operations, according to the company. It is also equipped with day and night cameras. The Harop is sometimes seen in sets of nine on land vehicles but can be configured to a different format for use at sea. The electro-optical assets of the Harop aid the man-in-the-loop operator and also provide for deep strike air superiority capabilities, IAI said. The Rotem is a vertical-takeoff-and-landing drone used by several countries. “The system provides a reconnaissance, observation and attack envelope with maximum autonomous performance, integrating a simple and intuitive operation interface that can be used by a single fighter from a touchscreen tablet,” IAI said. According to Yoel Guzansky, a senior fellow at the Institute for National Security Studies at Tel Aviv University, the recent Abraham Accords that saw relations improve between Israel and its neighbors, including the United Arab Emirates and Bahrain, has opened a niche in which Israel is more “kosher” to do deals with. That opens doors in the Gulf region and to Muslim countries globally, where Israeli sales would otherwise be viewed skeptically or be very sensitive. Other events boosting sales, he noted, include tension with Iran and the Nagorno-Karabakh conflict, during which Azerbaijan used loitering munitions against Armenian forces. Israel often doesn't identify the countries to which it sells defense systems because it doesn't want to appear to be part of conflicts, Guzansky explained. But “usually in reports when they don't disclose, it can be an Arab or Muslim country or Singapore, so usual suspects could be Taiwan, Singapore, Philippines, etc.,” he added. “Israel must be sensitive, to think hard at what kind of weapon systems and to whom [it is selling],” Guzansky said, as the government doesn't want to become entangled in a conflict between rival countries or have its arms end up in the hands of those for which they were not intended. Tal Inbar, an expert on defense and missile systems and a former chief of the Space Research Center at the Fisher Institute, also pointed to the recent Armenian-Azeri conflict as showcasing the use of loitering munitions. Amid the Abraham Accords, “I believe we will see [a] dramatic increase in [sales of] Israeli products.” Three and a half decades of experience in producing UAVs has led IAI to this point. Its family of systems also include the Harpy, Mini Harpy and Green Dragon. The Harpy was developed with an anti-radiation seeker to suppress surface-to-air missile radar. IAI predicts a future where militaries will use multiple layers of unmanned and remotely operated systems. The company sees the systems as appropriate for a variety of customers, from wealthy nations seeking high-tech weapons to those customers that require an affordable option to compensate for a lack of fifth-generation warplanes. https://www.defensenews.com/unmanned/2021/02/02/israeli-firm-sells-harop-rotem-kamikaze-drones-to-several-asian-countries
