Navy video illustrates lots of weaponry and boasts that Riverine Command Boats “pack a punch.”
What exactly is a Riverine Command Boat?
Old Salt Blog has the answer:
The Riverine Command Boat (RCB) is a design based on the Swedish Combat Boat 90. It is a highly maneuverable water-jet powered shallow-draft vessel that can operate at speeds of up to 40 knots. The design has been adopted by navies around the world. The Swedish Navy has 150 of the boats in service while Mexico has 48, Norway 20 and Malaysia 12, the US 6 and the UK 4.
How are they armed?
The Washington Post noted:
Nate Hale asks the obvious questions.
[T]here are a few serious questions surrounding the incident that remain unanswered. The two patrol boats (actually, Swedish-built CB-90s) were transiting from Kuwait to Bahrain when one (or both) of the vessels suffered a mechanical breakdown. Eventually, the boats drifted into Iranian territorial waters near Farsi Island, where they were detained by members of Iran’s Revolutionary Guards Corps (IRGC).
The most direct route from Kuwait to Bahrain is along the western side of the Persian Gulf; Farsi Island is more centrally located. If the boats were following a direct route, they must have drifted for some time before reaching the Iranian-controlled island. If only one vessel was affected by the engineering casualty, why didn’t the second boat take it under tow? Why weren’t additional assets–including airpower–dispatched by 5th Fleet Headquarters in Bahrain? The presence of Navy helicopters and F/A-18s overhead might have caused the Iranians to think twice.
And what about distress calls from the CB-90s to Navy command elements? Early reports suggested the Navy “lost track” of its assets. Perhaps someone can explain why the vast surveillance assets of the United States Navy couldn’t maintain radio and/or radar contact with a pair of patrol boats–or provide warning of Iranian activity. Major surface combatants (along with airborne assets) give the Navy an impressive SIGINT capability on the high seas; assuming we were tracking Iranian activities, it would be nice to know what information commanders had as the episode unfolded and how it impacted their decision-making.
There are also issues involving the commander of the boat element, believed to be the junior officer who issued the on-camera apology. Why did he offer no resistance when the Iranians began boarding his craft. Article II of the U.S. Military Code of Conduct states “I will never surrender of my own free will. If in command, I will never surrender the members of my command while they have the means to resist.” A CB-90 is heavily armed, with .50-caliber machine guns, GAU-19 mini guns and individual weapons for the crew. Obviously, no officer wants to see his command slaughtered; on the other hand, would it have been possible for the crew to resist, particularly with air support?
It’s also worth asking about the level of involvement by senior officials in Washington. Press accounts suggest that Secretary of State John Kerry was involved in the earliest contacts with Iran and spoke with his counterpart in Tehran no long after the sailors were detained. That quick response suggests the White House and State received early notification of the incident (reflecting the desired level of coordination). But it also begs another essential question: were senior officials micro-managing the episode from Washington, and decided early on to avoid a confrontation with Tehran at all costs.
Investors Business Daily calls for a congressional probe of the incident.
How can an advanced, ultra-agile U.S. combat boat suffer a “navigation error” that leads to a terrorist state capturing its sailors? Tehran just revealed military ineptitude warranting a congressional probe.
The Swedish-designed Combat Boat 90 can make the sharpest of turns at high speed, stop nearly on a dime, maneuver like magic and, with its Rolls-Royce jet-propulsion system, can speed along at over 45 miles an hour in rivers and shallow coastlines while transporting 18 amphibious troops.
But what good is any of that if it falls into enemy hands?
There is something fishy about how such a high-tech U.S. craft can “stray accidentally into Iranian waters due to a navigation error,” as Defense Secretary Ash Carter described it on Thursday to Univision. The Pentagon had previously claimed engine trouble for an incident that’s humiliated the U.S., as Iranian video showed to the world 10 American sailors on their knees at gunpoint.
A retired operations commander for the U.S. Navy’s Fifth Fleet in Bahrain, Christopher Harmer, told CNN the capture constituted “a severe failure,” charging that “either the naval leadership put these sailors in an impossible situation, or the sailors are professionally incompetent.” Harmer has researched the increased lethality of Iran’s submarine fleet for the Institute for the Study of War.
That one of the sailors would appear in an Iranian video apologizing may have actually violated the military’s Code of Conduct, which requires that a detainee give name, rank, serial number and age, but “evade answering further questions” and “make no oral or written statements disloyal” to his country “and its allies or harmful to their cause.”
Harmer told the Washington Times, “the U.S. Navy looks extraordinarily incompetent. … In its ability to transit boats without violating Iranian waters, they look incompetent to know how to deal with a mechanical malfunction, and now that they’ve been taken into custody, they’re apologizing.”
Harmer told CNN there was “no reason for a small vessel to be out that far and especially without escorting ships around it,” and “the Navy has to explain why you have small ships transiting 300 miles of open ocean.”
