Simultaneous Aircraft Launches from an Aircraft Carrier: Nimitz-Class Carriers and Relevance
When it comes to the strategic and tactical operations of aircraft carriers, the ability to launch multiple aircraft simultaneously is a crucial aspect. In this article, we delve into the intricacies of launching two F-18s or other aircraft types from an aircraft carrier, with a focus on Nimitz-class carriers. We will explore the deck operations, the necessity for safety, and the detailed process involved.
Simultaneous Launch Capability on Nimitz-Class Carriers
Modern Nimitz-class aircraft carriers, a significant backbone of the United States Navy, have advanced facilities for aircraft launch and recovery. These carriers feature four catapults at the bow and two on the angled portion of the flight deck. Such an arrangement allows for one catapult to launch from the bow and another from the waist catapult simultaneously, making it possible to launch two aircraft in quick succession.
Complexities of Simultaneous Launches
While it is technically possible to launch two aircraft simultaneously, concurrent operations on a single deck are not a common practice. The primary reason for this is the scrutiny and safety protocols involved.
Operational Protocol and Safety Considerations
Modern carrier operations involve a well-coordinated workflow, with each task carefully executed. The process is as follows:
Preparation and Coordination: Each aircraft is brought to the catapult by a yellows shirt, who also ensures that the aircraft is properly hooked up and ready to launch. The catapult shooter communicates with various team members such as the ordnanceman (red shirt), troubleshooter (checkered shirt), and the cat crew (green shirt), all of whom must give a thumbs-up to indicate that everything is in order.
Catapult Operation: Before launching, the cat crew signals for tension, and the pilot is notified that the aircraft is ready. Once the shooter confirms that the deck is clear and both ends of the catapult are safe, the shooter will launch the aircraft.
Simultaneous Operations: To perform a simultaneous launch, two shooters operate both the bow and waist catapults. Typically, two pilots perform clearing turns, with one turning to the left and the other to the right, to avoid collision. The most challenging aspect is the "double hooking" maneuver, a technique that involves a highly skilled and experienced team to execute a second launch immediately after the first.
While simultaneous launches are technically possible, they are not frequently undertaken due to the increased risk factors involved. The time gap between launches is often kept less than a minute to ensure safety and coordination.
The Art of Simultaneous Launches
Despite the complexity, simultaneous launches are a critical skill that ensures effective carrier operations during large launch surges. This involves the coordination of shooters, yellow shirts, and other deck crew to ensure that aircraft can be launched in quick succession.
Challenges and Limitations
The simultaneous launch of two aircraft is contingent upon several factors, including the aircraft's type, wing span, and the load of wing stores. Wind conditions over the deck must support safe flight for all aircraft involved. Different aircraft configurations require different minimum wind speeds, which are managed by ensuring the wind over deck is sufficient for all planes being launched.
To achieve this, two launching officers (shooters) work simultaneously, each responsible for their set of catapults. During the early stages of a launch, the shooters pre-determine the order of shots, and once the first few shots are launched, they work based on the readiness of the planes. The yellow shirts, who coordinate the deck activity, ensure that planes are fed to the correct catapult at the right time.
Some aircraft configurations cannot launch from Cat 4 due to space and obstacle restrictions, further emphasizing the need for careful planning and coordination.
In summary, while it is technically possible to launch two aircraft simultaneously from a Nimitz-class carrier, it is a highly specialized and risky operation. The focus on safety and coordination is paramount, and such launches are typically conducted when time gaps are minimized to maintain operational efficiency.
