The Maritime Museum of San Diego recently acquired DeepFlight I, a unique “flying” underwater submersible developed in the late 1990s. You can read more about this amazing, advanced submersible here.
Visitors to the San Diego museum might be astonished to learn that this one-of-a-kind prototype appears in every episode of Star Trek: Enterprise!
DeepFlight I can be seen momentarily in the Star Trek: Enterprise introductory sequence, which begins every episode. The sequence depicts the evolution of human technology and exploration. DeepFlight I appears at the 34 second mark here!
Super cool!

Today is officially the 250th birthday of the United States Navy. On October 13, 2025, the U.S. Navy was established by the Continental Congress.
Needless to say, the Navy has a very large presence in San Diego, with important bases that include Naval Base San Diego, Naval Base Point Loma, Naval Air Station North Island (where naval aviation was born), and Naval Amphibious Base Coronado. Over the years, countless sailors trained at the old Naval Training Center San Diego, and have deployed from San Diego’s harbor on ships in both wartime and peacetime. Until 1997, Top Gun pilots trained at Naval Air Station Miramar.
I’ve published a wide variety of blogs concerning the U.S. Navy in San Diego. Given today’s 250th anniversary, I thought this would be a good time to revisit some of those past blog posts.
Click the following links to bring back some U.S. Navy memories…
Check out what arrived at the Maritime Museum of San Diego yesterday! This super cool “Deep Flight” submersible!
This electric, one-man submersible was developed about 15 years ago by Hawkes Ocean Technologies. It’s now on display in the museum’s steam ferry Berkeley, in a spot where many model ships can be viewed.
I’m reasonably sure this is DeepFlight I, a submersible that served as a technology testbed for DeepFlight II. You can see a photo and learn more about Hawkes Ocean Technologies on this website.
The exhibit is so brand new, the submersible is still on rollers and there’s no information sign in the museum yet. (I was told that to roll the submersible into the Berkeley, part of the museum’s front desk had to be removed!)
While I don’t know too much right now, I’ll endeavor to learn more tomorrow when the Maritime Museum of San Diego has a special member event. I’ll provide more info here in an update.
But look at how cool this thing is! Imagine lying prone, squeezed inside the narrow craft, down in the mysterious depths of the sea, flying along silently like an underwater aircraft, water and sea life all around!
UPDATE!
A few days later, I noticed two of the historic submersible’s wings had been reinstalled.
A sign also points visitors to a cool YouTube video concerning the DeepFlight I. Watch it here.
UPDATE!
A sign appeared later. I was surprised to learn DeepFlight I briefly appears in the introductory film sequence of Star Trek: Enterprise!
An impressive yacht has been docked on San Diego’s Embarcadero for weeks now. Perhaps you’ve seen it, just north of the Maritime Museum of San Diego.
As I walked past the yacht this morning, I was surprised to see its side open and gentlemen working on a super cool, bubble-like submersible. For a moment I thought I had wandered into a documentary about ocean exploration–or a science fiction movie!
In fact, I was looking inside the Hodor, a 66-meter catamaran that this article describes as the world’s largest floating toy box! Among the toys it holds is the three-person Seamagine Aurora-3 submersible, which I spotted in its open “submarine garage” while walking down the boardwalk. Other toys include a helicopter, motorcycles, and ATVs!
Hodor is support vessel of larger privately owned superyacht Lonian, which is also docked in San Diego.
You never know what cool thing you might discover during a morning walk!

The world record deepest diving submarine was cleaned today. The USS Dolphin at the Maritime Museum of San Diego had it’s outer hull scraped clean of algae and barnacles. It’s an operation that must be carried out every four months or so.
The specially designed USS Dolphin (AGSS-555) can list many historic achievements, including several world firsts. She retains the record for the deepest dive by an operating submarine. Learn more about her at the Maritime Museum of San Diego website here.
Nine years ago I climbed down into this incredible submarine and took interior photos. If you’d like to see them, click here. Better yet, head down to the museum and enjoy the experience yourself!

Check out these three cool murals in North Park! They’re painted on the parking lot side of the Queen Bee’s Art and Cultural Center building, north of University Avenue off Ohio Street.
The three murals, from left to right, depict a graffiti-style North Park, The Beatles’ yellow submarine, and cosmic mandalas with music-loving bees!
Around the corner, at the entrance to Queen Bee’s, you’ll find more fun artwork…

Every so often, a very unusual, one-of-a-kind ship will dock on San Diego’s Embarcadero. Today I saw a unique ship with the peculiar name DSSV Pressure Drop, so I had to check it out!
It turns out DSSV (Deep Submersible Support Vessel) Pressure Drop, a privately owned ex-US Navy ship, is absolutely extraordinary! Last year its submersible, called Limiting Factor, made the deepest manned dive ever in Earth’s oceans–it descended 10,928 meters into the Challenger Deep in the Mariana Trench!
This historic dive and others have produced important scientific research, such as mapping of the ocean floor and retrieval of deep sea specimens–including completely new species of living organisms!
The numerous exploits of DSSV Pressure Drop and its adventurous owner Victor Vescovo make for great reading. Here’s a recent article that provides a lot of background and detail.
I was told DSSV Pressure Drop will be hanging around San Diego for a couple of months, so if you happen to walk along the Embarcadero just north of the Maritime Museum of San Diego, keep your eyes peeled!

It’s widely known that Coronado’s North Island is the birthplace of naval aviation. But did you know that shortly before World War I, Coronado was also home to a training school for submariners?
Camp Richardson, which was located on a block of First Street just north of the Ferry Landing, served as the homeport of the United States’ very first Pacific Submarine Fleet. This is one of many interesting facts you’ll learn should you enjoy A View from the Periscope, which is the current exhibit at the Coronado Historical Association‘s museum.
A View from the Periscope focuses primarily on twenty-eight works of art. The Coronado Historical Association’s website explains how these pieces of artwork from the Naval History & Heritage Command’s Navy Art Collection are on loan for the exhibition. Throughout the museum gallery visitors can view paintings of submarines in different settings and their working crews. The website further explains that many of the artists featured are affiliated with the Navy’s Combat Art Program, which places artists on board navy ships on duty and in combat.
But there’s much more to discover in this exhibition! When I walked through it a few days ago, what interested me most were displays that concern local history.
Not only did I learn about short-lived Camp Richardson, but I was surprised to read how the submariners in training, as they practiced diving and firing torpedoes, would put on pre-announced shows in San Diego Bay for tourists staying at Coronado’s Tent City!
I was also surprised to learn that a Coronado artist, a member of the San Diego Fine Arts Guild, was instrumental in successfully camouflaging naval vessels during World War II.
His name was Dayton Brown. His novel approach to camouflage involved mimicking the natural environment, eventually utilizing only two color shades like Haze Grey or Ocean Gray.
Until I visited this exhibition, I had no idea!
A View from the Periscope continues through January 2023.

A San Diego memorial to U. S. Navy submariners lost at sea, the 52 Boats Memorial, needs your help. Some of the monuments that line two pathways at NTC Liberty Station in Point Loma are badly damaged.
I was walking through Liberty Station today when I took these photos. A search of the internet brought up this very recent article, which describes one man’s effort to restore broken markers, like those in my photographs.
The original markers need to be replaced with more durable concrete duplicates. There are already sufficient funds to undertake this endeavor–what they need is someone who can make concrete and use the molds…Ideally, the person or business also would be able to deliver and install the heavy monuments…
I first blogged about the 52 Boats Memorial over eight years ago here. It’s a very powerful Veteran’s memorial. Certainly someone out there can help.
Should you walk from the parking lot by Birch Aquarium at Scripps Institution of Oceanography to the popular attraction’s entrance, you’ll see what looks like a small submarine. On its side is written Star III.
Star III is actually a submersible that was used for undersea studies back in the mid-20th century.
I looked at the cool little marvel of technology and wondered about its history.
A nearby sign provides interesting information concerning the submersible, which was built by General Dynamics.
When I got home, I found a book published in 1968 by the Naval Oceanographic Office titled Undersea Studies With the Deep Research Vehicle Star III which you can preview here. It concerns a series of 21 dives off Key West Florida in March 1967…to evaluate the Star III system as a platform from which to conduct underwater photogrammetric and various surveying tasks.
I also found the following old public domain photograph of Star III suspended above the water from a seagoing vessel.
Launched in 1966, Star III was capable of carrying a two-person crew and as much as 1,000 pounds of scientific equipment to a depth of 2,000 feet. The sub and its occupants could remain underwater for up to 120 hours…
