Seaman Ryan Castillo, a native of San Diego, California, with family roots in the Philippines, is continuing his family’s legacy of hard work and service as a U.S. Navy sailor assigned to the USS Indianapolis, a littoral combat ship operating out of Naval Station Mayport.
For Castillo, his Filipino heritage and the example set by his family have played a major role in shaping his approach to service.
“My family immigrated from the Philippines,” Castillo said. “Growing up watching my parents work every day is what really motivated me. That stuck with me for life. Being first-generation American, I learned early that opportunity isn’t owed to you; it is earned through showing up and doing the work when nobody’s watching. That is exactly what I bring to the Navy every day: honor, courage and a commitment to something bigger than myself.
“If my story can inspire another first-generation kid to believe this path is possible for them too, I am honoring everything my family gave up to get me here.”
Following His Brothers’ Footsteps
Castillo joined the Navy two years ago, inspired in large part by his two older brothers, Ryjohn and Randy, who also served in the Navy.
“My inspiration to join the Navy was my two older brothers, Ryjohn and Randy, who served in the Navy as well,” Castillo said. “I saw the personal development it engraved into them as individuals and the success and benefits they were able to achieve throughout their career, so I wanted to follow in their footsteps to create the same pathway for myself and also be an example for others.”
Today, Castillo serves as a logistics specialist, supporting the Navy’s mission through the vital work of managing and coordinating resources.
Serving Aboard USS Indianapolis
Littoral combat ships such as USS Indianapolis are designed to operate in near-shore environments and counter 21st-century threats. These vessels can operate independently or as part of a networked battle force in high-threat scenarios alongside larger, multi-mission surface combatants, including cruisers and destroyers.
The Navy’s global mission also carries broader economic and security implications. With 90% of global commerce traveling by sea and access to the internet depending on the security of undersea fiber-optic cables, Navy officials emphasize that the prosperity of the United States is closely connected to recruiting and retaining talented people from across the country’s diverse communities.
Turning Hard Work Into Achievement
During his military career, Castillo has already reached several milestones that he considers especially meaningful.
“My proudest accomplishments have been winning Blue Jacket of the Quarter early in my career and being awarded the Navy and Marine Corps Achievement Medal,” Castillo said. “I earned all of that simply by living out what the Navy instilled in me, which is integrity and a strong mindset, especially when things got tough. I am proud of it because it is proof that consistency and character get noticed.”
Castillo serves in a Navy that operates around the world and around the clock, carrying out missions intended to promote the nation’s prosperity and security.
‘An Opportunity That Not Everyone Gets’
For Castillo, wearing the Navy uniform represents more than a career. It is also a way to give back to a country that has provided opportunities for his family.
“To me, serving in the Navy means being blessed with an opportunity that not everyone gets and knowing that I never take a single day in this uniform for granted,” Castillo said. “It’s a chance to give back to a country that has given my family so much, and to stand as an example for my friends and family, especially the ones back home who are watching and dreaming of more opportunities.”
Grateful for Family and Mentors
Castillo also credits his family and Navy leaders for helping shape his journey.
“First and foremost, I want to thank my family,” Castillo said. “My mother, Josephine, and my brothers, who built my thick skin from a young age and gave me the strong work ethic I bring to everything I’m tasked with.
“I also want to thank my leadership, Lt. j.g. Boyadjian, Senior Chief McGuire, Petty Officer 1st Class See, Petty Officer 2nd Class Magloire, and so many others. I am incredibly fortunate to have served under their guidance, and I am grateful for everything they’ve mentored me through to become the person I am today.”
