Antártica 1 is a Polar Class 5 icebreaker currently under construction in Chile.[4][5][6] When completed it will replace Contre-Almirante Oscar Viel Toro, a second hand vessel, first commissioned in 1960. Accounts differ as to when construction of the ship began. The Santiago Times reported the first steel was cut in May 2017, while Jane's Navy International reported construction began in August 2018.[1][7]

Antártica 1 will be 111 metres (364 ft 2 in) long, and have beam and draft of 21 metres (68 ft 11 in) and 7.2 metres (23 ft 7 in).[1] She will displace 13,000 tons. Her maximum speed will be 15 knots (28 km/h).

She will have the capacity to house 150 crew and researchers or passengers.[1]

She will be able to sail through one-year ice, one meter thick, at 2 knots (3.7 km/h).[1]

Maritime Executive reports that when completed, in 2022, she will be comparable to Argentina's ARA Almirante Irízar.[8]

'Antártica 1 will have greater capabilities for supporting high-level, onboard scientific activities which will allow it to break from the seasonality of scientific work, accessing data in real time, and analyzing the results obtained while underway,' Retamales said. 'It will have modern, hydroacoustic equipment, such as echo sounding, sonar, an ocean floor profiler, a current profiler, and a high-precision acoustic positioning system. It will also be outfitted with biology, microbiology, and chemistry labs, and it will have the means for collecting, storing, and preserving water samples and samples from the seabed, with the capacity provided by modern and spacious refrigeration chambers,' he added.

Chilean defense sources said the icebreaker project to replace the 6.500 ton Almirante Viel include an initial budget of 150 million dollars and building the new 8.000 ton ice breaker with foreign technical assistance in local shipyard Asmar. Meanwhile, Marinero Fuentealba, an 1,800-ton offshore patrol vessel with reinforced hull for polar operations, is being completed by ASMAR for commissioning in August.
