The Polar regions (the Arctic and Antarctic) are seeing more natural resources and shipping lanes become available due to reduced ice coverage as well as increased presence from China and Russia. The U.S. Coast Guard must also increase its presence to protect U.S. sovereignty and economic interests. Icebreakers are essential for providing this presence in the Polar regions. However, the Coast Guard’s icebreaker fleet currently consists of only two ships: one medium and one heavy polar icebreaker. This capacity is unable to meet the growing national requirement for icebreaking and presence.
In the Antarctic, heavy icebreakers specifically are necessary to support the National Science Foundation with the annual resupply of the McMurdo research station, the primary research facility in the Antarctic, and to support requests from the U.S. Department of State for enforcement of the Antarctic Treaty of 1959 because the thick ice makes it difficult to access this area.REF
Current Economic and Security Environment in the Polar Regions
As an Arctic nation, the U.S. has important economic interests in the region, including a large exclusive economic zone (EEZ) containing numerous natural resources like minerals, oil, and gas. Approximately 13 percent of undiscovered oil resources and 30 perecnt of undiscovered gas resources are located in the Arctic.REF Melting ice has opened up seasonal arctic shipping lanes for potentially more efficient transit of goods between Asia and North America, and has provided greater access to large deposits of energy and mineral resources that were not previously accessible. Adventure tourism and transpolar flights are also increasing the activity levels in the Arctic.
Additionally, Russia has made aggressive claims to natural resources under the icecap, arguing that its continental shelf extends far beyond its recognized territorial limits, and has invested heavily in military assets capable of operating in the Arctic.REF China is increasing its presence in both Polar regions as well, sailing its icebreaker through the Arctic recently and constructing a second icebreaker.REF These activities increase the level of competition and could place U.S. resources at risk for exploitation by foreign powers if the U.S. cannot effectively shape events.
The Icebreaker Fleet
Icebreakers perform nine of the eleven Coast Guard statutory missions, including law enforcement, search and rescue, and defense missions. The only two missions they do not perform are migrant and drug interdiction operations, simply because those do not occur in the Polar regions. Icebreakers are the primary U.S. instrument in polar international cooperation, competition, and conflict deterrence.REF The U.S. cannot shape events in an area it cannot physically access.
The current icebreaker fleet is incapable of effectively meeting current mission requirements. From 2010 to 2016, the U.S. only fulfilled 78 percent of icebreaking requests.REF The Coast Guard currently operates one heavy polar icebreaker, the Polar Star, and one medium polar icebreaker, the Healy. The Coast Guard’s other heavy polar icebreaker, the Polar Sea, is no longer operational and serves as spare parts for the Polar Star.
Commissioned in 1976, Polar Star was designed for a 30-year service life. The Polar Star requires extensive dry-dock maintenance following the annual resupply of the McMurdo research station in the Antarctic, making this its only annual mission. It completed a service life extension in 2012, designed to extend its service to 2023, when the first new icebreaker is due to be completed.REF Even after undergoing this maintenance cycle, it is unclear whether the icebreaker will last until then, creating a possible capability gap.REF
While the Healy, commissioned in August 2000, is more modern than the Polar Star, it has less icebreaking capability, and struggles to support heavy icebreaking operations like the Antarctic McMurdo resupply, and is incapable of reaching certain areas of the Arctic in all seasons.REF It can only provide seasonal presence in the Arctic as it cannot break through thick ice (greater than 4.5 feet) at a sustained speed.
In order to assure the U.S. meets its strategic objectives in the Polar regions, the Coast Guard needs a fleet of icebreakers. Its official requirement calls for up to six new polar-class icebreakers, three heavy and three medium. Coast Guard Commandant Admiral Zukunft acknowledges that some flexibility comes with that requirement, as six heavy icebreakers would better fulfill all of the mission requirements.REF
The requirement itself comes from the 2010 High Latitude Study, which the Department of Homeland Security affirmed in a Mission Needs Statement in June 2013.REF A fleet of six new polar-class icebreakers would allow year-round access to the Arctic and redundancy and self-rescue capability, as well as the ability to meet national strategic objectives in the Antarctic.REF The Coast Guard partially based this requirement on the concept commonly used by the U.S. Navy that it takes three ships to ensure one ship is constantly deployed. Typically, one ship is deployed, another is in training, and the final ship is undergoing major maintenance.REF
The new heavy icebreakers must be able to break 6 to 8 feet of ice at a continuous speed of 3 knots, and possess the ability to break 21 feet of ice using the back and ram method.REF Many of their planned features are similar to those of the Polar Star, but with key improvements. The new icebreakers are envisioned to have improved reliability and maintainability, ship control and communications, as well as increased space, weight, and power margins to add scientific or defense equipment later if the need arises.REF These changes are crucial for addressing the shifting mission needs on ships that will be in service for over thirty years.
Recent Activity on Upgrading the Fleet
The program for the design and construction of a new polar-class icebreaker began in 2013 with a budget request for $23 million. The Coast Guard has taken steps to advance the program. In August 2016, the Coast Guard created an integrated program office with the U.S. Navy in order to leverage the Navy’s shipbuilding expertise to assist in the acquisition effort. It also engaged with the shipbuilding industry in order to get a better understanding of the domestic shipbuilding market.REF
On March 2, 2018, the Coast Guard’s Integrated Program Office released a Request for Proposals for the first heavy icebreaker to industry for the advance procurement and detail design, with options for detail design and construction for up to three heavy polar icebreakers.REF The Coast Guard’s fiscal year (FY) 2019 budget requests $750 million to award the detail design and construction contract for the first new heavy icebreaker, as well as another service life extension for the Polar Star.REF
In order to meet the security needs in the Polar regions, Congress and the Coast Guard should:
- Fully fund the Coast Guard’s budget request of $750 million for FY 2019. The Coast Guard now estimates that the cost of each icebreaker will be well under the original estimate of $1 billion. Given the important U.S. interests in the Arctic and Antarctic and increasing competition, it is essential to provide the Coast Guard with the necessary funding for this first icebreaker, followed by the remaining five.
- Acquire the first three heavy icebreakers using a block buy strategy. A block buy strategy could save upwards of $200 million for the program.REF While some program flexibility is lost using this strategy, it is made up for by lowering the overall cost of the program.
- Assess whether to acquire medium icebreakers or three more heavy icebreakers of common designto reach a total of six. According to a study conducted by the National Academy of Sciences, a fourth heavy icebreaker could cost $692 million versus $786 million for the first in class medium icebreaker, a savings of nearly $1 million for the first ship alone.REF A fleet of heavy icebreakers would also provide more capability, as they can complete the entire suite of icebreaking missions, and reduce maintenance costs.
The Coast Guard requires a fleet of new polar-class icebreakers to defend America’s security and economic interests in the Polar Regions. Icebreakers are crucial for meeting the separate challenges of operations in the Arctic and Antarctic, and the current fleet is not capable of meeting those challenges effectively. The Coast Guard has made progress on this program recently, and the proposed new ships will have better capabilities for securing America’s interests for the next several decades. Because of this, Congress should fully fund the six new icebreakers needed for this program.
