Sailor expands her horizons with the Royal New Zealand Navy

Ōtaki-born sailor Sean Byers-Cook joined the Royal New Zealand Navy to expand her horizons. Over the last two years she has crossed many of those horizons.

13 September, 2024

Leading Combat Systems Specialist (LCSS) Byers-Cook is serving aboard frigate HMNZS Te Kaha, which is undergoing an intensive training schedule in preparation for overseas deployment next year.

After finishing school LCSS Byers-Cook worked in civil construction and volunteered for Hato Hone St John ambulance service. 

“I was really motivated to expand my horizons and try something new,” she said.

“It led me to the Navy recruitment website. I was initially going to leverage my volunteering experience and become a medic, but my eye was drawn to the combat systems specialist trade.” 

She joined in 2017.

Combat systems specialists operate military radars and sonars to understand what ships, aircrafts and submarines are in the vicinity of a warship, whether friendly or a threat. 

They are trained to use remotely controlled weapon systems to defend the ship, and act as a communications link between maritime helicopters and ‘home plate’ (the ship).

LCSS Byers-Cook now has several overseas deployments under her belt. She recently returned from Exercise Rim of the Pacific, the world’s largest maritime exercise, in Hawaii.

As a battle watch captain, she worked in a headquarters staffed around the clock, helping coordinating the logistics for the “tanker task force”, tracking fuel, analytics and fielding requests from ships at sea.

She said a career highlight was a South East Asian deployment in frigate HMNZS Te Mana in 2023, particularly a port visit to Ho Chi Minh City, Vietnam, where the culture and hospitality of Vietnam left an impression.

“There was this wonderful reaction to our ship’s multi-cultural performance, which was televised. I remember later seeing some locals imitating the actions we’d done.”

All sailors like time off to explore. In Hawaii she swam beaches and went on numerous hikes around the island. 

“The tropical climates I’ve been to have been a big change from a deployment in Canada during the Covid-19 lockdowns in the middle of winter.”

On her return LCSS Byers-Cook assisted HMNZS Canterbury for two weeks with helicopter exercises, before joining Te Kaha.

Despite all the travel, she still misses Ōtaki. 

“I go back whenever I can, usually at least twice a year, I still have family still there and call it home.”

She is grateful for the experiences the Navy has provided.

“What I enjoy most about the Navy is interacting with people from different backgrounds, areas and demographics. I like to discuss new ideas and hear different perspectives.”
