Thomas Leo Clancy Jr. was an American novelist and military-political thriller pioneer. Raised in a middle-class Irish-American family, he developed an early fascination with military history. Despite initially studying physics at Loyola College, he switched to English literature, graduating in 1969 with a modest GPA. His aspirations of serving in the military were dashed due to severe myopia, leading him instead to a career in the insurance business.
While working at a small insurance agency, Clancy spent his spare time writing what would become The Hunt for Red October (1984). Published by the Naval Institute Press for an advance of $5,000, the book received an unexpected boost when President Ronald Reagan praised it as “the best yarn.” This propelled Clancy to national fame, selling millions of copies and establishing his reputation for technical accuracy in military and intelligence matters. His meticulous research and storytelling ability granted him access to high-ranking U.S. military officials, further enriching his novels.
Clancy’s works often featured heroic protagonists such as Jack Ryan and John Clark, emphasizing themes of patriotism, military expertise, and political intrigue. Throughout the late 1980s and 1990s, he became one of the best-selling authors in America, with titles like Red Storm Rising (1986), Patriot Games (1987), Clear and Present Danger (1989), and The Sum of All Fears (1991) dominating bestseller lists. Several of these were adapted into commercially successful films.
In addition to novels, Clancy co-authored nonfiction works on military topics and lent his name to numerous book series and video game franchises, including Rainbow Six, Ghost Recon, and Splinter Cell. His influence extended beyond literature, as he became a part-owner of the Baltimore Orioles baseball team and was involved in various business ventures, including a failed attempt to purchase the Minnesota Vikings.
Politically, Clancy was a staunch conservative, often weaving his views into his books and publicly criticizing left-leaning policies. He gained further attention after the September 11 attacks, discussing intelligence failures and counterterrorism strategies on news platforms.
Clancy’s financial success was immense. By the late 1990s, his publishing deals were worth tens of millions of dollars. He lived on an expansive Maryland estate featuring a World War II Sherman tank and later purchased a luxury penthouse in Baltimore’s Inner Harbor.
He was married twice, first to Wanda Thomas King, with whom he had four children, and later to journalist Alexandra Marie Llewellyn, with whom he had one daughter.
Tom Clancy passed away on October 1, 2013, at the age of 66 due to heart failure. His legacy endures through his novels, their adaptations, and the continuation of the Jack Ryan series by other writers.

This is literally the worst book I've ever read.

It is not really a novel, it is (literally) a half-assed attempt at turning a strategy guide for a video game into a novel.

Normally I would have given up about a quarter of the way through, but I was trapped on a flight with it.

Very, very bad indeed.

This book is super boring and I could only get to page 56 before I gave up on it. The Hunt for Red October is my fav Tom Clancy book and the only one I've read. I have tried to read other books of his like Rainbow Six but I just can't pay attention. I figured I'd be ok with another book about submarines. Annnnnd I was totally wrong. It only has one character with a name who is not developed at all. I can't believe this was marketed as a strategic guide for sub warfare. I'm pretty sure it's over simplified. A person might as well just read a fiction book or Wikipedia. Heck, I'd rather read Wikipedia or articles about the different weapons, planes, subs, etc. The book "explains" things in a way that after you finish the sentence, you still don't know what you just read. For example:

"Otherwise, she would have a tendency to pitch with a ten-second period due to a ninety-foot wavelength of sea state four."

Uh, what the fuck? Is he talking about the oscillation if the waves? When he means wavelength, does he mean the distance from top of a wave's crest to another wave??? I'm having to use my science background to figure this crap out and there is never any explanation of the numbering of sea states prior to this sentence.

Another gripe. The dialogue, though sparse, is stupid. It's like reading the script of a Michael Bey movie.

"Phoenix is locked on. That submarine captain sure owes us one."

"I guess we just broke Murphy's law," Mack replied, his voice as calm and efficient as ever.

Seriously. How can a voice be EFFICIENT?!

I can see why this was collecting dust in a used bookstore....and guess what? It's going back.

Not really a novel, instead its 15 scenarios for submarine combat in a war between the US and renegade elements of the chinese military. The submarine cheyenne ends the war with over 60 confirmed kills of chinese combat vessels and if the chinese military was actually that bad their sailors should save themselves the effort of putting to sea and shoot themselves. The captain Mack is 2 dimensional, which gives him at least 1 dimension more than anyone else in the book. The closest we get to a personal detail is when he wishes he could go to a steakhouse he knows in Taiwan while in port there. Still if you like military techno-thrillers ans have read all of Tom Clancy's other books (all of which are better than this one) it'll pass a few hours.

I was suckered! Didn't read the fine print-not a novel but a " novelization " of a video game! If you can't imagine how boring it is reading a description of somebody else playing a video game, then try this book. I've liked some of Clancy's other books, but now that I know he's franchised his name for a quick buck, I'm on guard. Never again.

Also, one of the 'China is the new Russia' books, an early one. Truely a nightmare of a book.

Clancy’s books often hinge on the absurd, but how stupid does he think foreign militaries are? Does he really think that one submarine can take out like a dozen plus enemy subs without a scratch?

Also, the phrase “ready torpedo tubes one and two in all aspects including opening the torpedo tube doors” is now imprinted in my brain, and not in a good way

Piss poor excuse for a book. How can a book be based on a game? It is perfectly set up where in between each paragraph you have a battle scene and something exciting happens. Absolutely terrible idea to make a game and then a book based off of each chapter. I would be ashamed if I were Tom Clancy.

That's it, this is like the worst novel i've ever read. it is stupid, one sided. what is the point of writing a novel where one SSN is taking the entire navy of another nation?!!!
I couldn't finish the book, after half of it i felt that continuing the book is much harder than i could take and after all reading is supposed to be a fun thing not a challenge.

This is a really bad book. Allow me to rephrase that: if you are looking for an exciting novel centered on  submarine warfare, you need to keep looking. SSN is not the answer to your search. As a novel, it’s really poor. The back cover blurb really, really oversells the book.

On the other hand, if you’re writing your own novel and doing research on late-Cold-War era submarine operations, capabilities, and tactics, it’s a useful book. Tip: buy the Kindle Edition so you can search for words. If there’s anything I expect from Clancy it’s accuracy, and SSN does not disappoint on that score. As a writer, I’m often wondering what would the conversation in the control room sound like when the captain is confronted with various tactical scenarios. I’ve saved multiple hours of research on questions like that with this book. But most readers are simply looking for a good novel. This isn’t it.

In fact, it really isn’t a novel at all. It amounts to the proper way to play out the fifteen scenarios in the video game by the same name. As fiction goes it is frankly boring. The good guys always win, the bad guys always make conveniently stupid decisions, there are almost never any hardware failures. The captain is a cardboard-cutout character and the rest of the crew do not even merit names. The submarine, the Cheyenne (SSN-773), a Los Angeles-class fast attack boat, has more kills than a machine-gunner taking down a feedlot of cows, and receives about the same amount of effective return fire that you would expect from a herd of trigger-happy bovines who don’t happen to possess any weapons.

Clancy is one of my favorite military adventure/action writers. Everything else I have read by him is edge-of-your-seat-miss-your-bedtime-can’t-tear-yourself-away good. But not only is SSN not his best outing, this book sinks at its moorings, never even pulling away from its berth. You want a good novel? Mothball this hulk and keep looking. Two stars.

I am a big fan of Tom Clancy's writing ever since I first read The Hunt for Red October. However I was horrified when I read about classified information being released in the book and I confess to being confused that it was published by the Naval Institute Press.

In fairness to this book, which covers a mythical war with China which involves mostly submarines, submariners are fond of quipping that there are only two kinds of ships: submarines and targets. They aren't far from being wrong either.

Being involved in various government plans to attack enemy submarines for several years, one has to admit that if submarines do not want to be found, they don't get found unless they want to launch something. This is especially true of the American fleet. We really do carry sonic records of the submarines we have ever known about. Not only do we do this, but the records are amazingly accurate and we can hear them a long way away.

As someone else mentioned, this book is not perfectly representative of what life is aboard a submarine. If it were, it would only raise our appreciation for what these men go through to protect our sleeping butts so we can go protest the war or something. For me, it's ok if it isn't accurate because it's exciting.

The people in this story are not, as another reviewer suggested, well developed. Perhaps Clancy just wished to write a story which was short and to the point. One of the reasons for the brevity of character is that these men really are that focused on their jobs, at least while working.

For those who have no interest in thermal layers and the various techniques used in modern submarine warfare, please stay away. For those who want an excellent snapshot of what all of it is like, albeit with a sanitized view, then I recommend it highly. I have to admit that I'm one who cheers when we win.

I believe the wife picked up the copy we have from a freebie table somewhere. I found myself reading it in the car while she was doing some shopping (sleeping kids in the back). Reading it was preferable to just sitting there, but that’s about the best I can say for it.

The time is the mid-90s. Due to Chinese aggression, the U.S. has gone to war in the Pacific, although it appears that practically the entire war effort is carried by a single nuclear-powered submarine (and the supply ships that periodically restock it with torpedoes). To the best of my recollection, the only casualties on the U.S. side are a helicopter and an older submarine that ought to have been decommissioned. It was hard to keep track of all the enemy losses, but they were so numerous and repetitive and the engagements were so free of any real sense of danger as to put me in mind of a slow-moving game of whack-a-mole. I hope no one who reads this fantasy (or plays the CD-ROM game associated with it) supposes that actual combat would ever be this easy.

Clancy appears to have a good handle on the details of running a sub, and that enables him to crank out no end of the following kind of prose:

Cheyenne was already beneath the first layer. In less than three minutes, Cheyenne was at flank speed, on course 175, and at one thousand feet, beneath the second layer. There was a deep sound channel present, something Mack would have known if he'd been able to acquire SSXBT information. As it was, he learned of its existence from the sound velocity profiler.

In this book, he gives no indication of having a grasp of anything else.

This book was based on a computer game. It follows a submarine commander as China and the USA fight a war. There was a photo section that when I looked at the pictures told me how the story played out. It was interesting and fun to read... but also very predictable and repetitive. The following phrases appeared over a dozen times, Literally cut and pasted throughout the book:

"Make tubes one and two ready to fire in all respects, including opening the outer doors."

"Tubes one and two are fired electrically."

"Conn, sonar, units from tubes one and two running hot, straight and normal."

>>> Spoiler <<<

USA wins, China loses, skipper gets promoted to Admiral, no injuries to crew or damage to USS Cheyenne. But You'll get all this if you look at the pictures- presumably capture screens from the video game.

Not Clancy's best work.

The only really interesting material here is in the interview material at the end of the book. The actual fictionalized action reads like what it is, a continuous action video game, with no depth.

Several of the technical aspects of a nuclear boat and crew operations are presented in a kind of "yep: check that fact got included" manner.

The concept of China invading the Spratley islands despite the Philippines' insistence of ownership is a fact that is currently playing out, so the contextual basis of the book was accurate, and doesn't by itself make the book interesting.

eponymous sentence:
p11: Given the hull number SSN-773, Cheyenne was the last of sixty-two Los Angeles class nuclear attack submarines to be funded by Congress.

quotation mark:
p276: "...In addition, Li and I are once again communicating with each other--cautiously, I might add--but we are closer to negotiations.
Mack nodded again, but remained silent.

A video game adaptation! Must be the first of its kind.

Its no Hunt but, boy, the scenario is just chillingly plausible--at that time, at least. At present, Spratly Islands are still being contested.

Excuse my French, but sheer shit. Whilst the political plot had good legs, it was barely explored, and the obsession with 'boy's toys numbers' (Mk48, PL765, ABC 987 etc ad nauseam) left me breathless with despair and reminded me why I hadn't read a Clancy in years. Yawn

I finally found a submarine book I didn't really like. DNF

The problem is that since this was written based off of a video game it really feels like its just someone describing what is happening on the video game. Also the game is set to easy. I realize its a thing now that people read books that sound like games but I don't get it and can't get into the genre at all. This is like a proto litRPG.

There is never any sense of danger or worry for any of the characters. The bad guys always do stuipd things in order to make the heros seem amazing. The hero boat never has any drama onboard, and the crew of the boat are just flashing lights or pre-recorded audio bits right from the game. There is no sense of depth. No... there there.

I got about halfway before giving up. So if you like written descriptions of someones play through of a book grab this. Otherwise..... give it a miss.

If there was ever evidence that video games stories are not worth adapting, this is it.
This was probably ghost written as it is thin and lacks purpose. The interview at the back is interesting, but not worth reading the rest to get to it.
The fact that only 3 or so characters are named shows how little developement there is. Laughable feats are achieved such as the USA sustaining no damage in a navel battle (law or averages indicates that some losses would be sustained even if it wasn't against a superpower like china). Most of it is just boring and rips off elements better explored in the "Northern Resource area" trilogy (Debt of Honor, Executive Orders, Bear and the Dragon).
Waste of time and (minimal)effort.

An astounding premonition of the future, one of Tom Clancy's many.

Alas, this work is not Clancy at his finest - SSN is repetitive and fails to develop a reader affinity for the main protagonist Mack.

Clancy is most effective with intricate plots and complex characters - which are not present here.

This book was thin. It would have been about two pages long if Clancy left out the command recongnitions. Yes, I get it is the Navy - but come on - give the reader a break. Establish the protocal and move on.

For a Tom Clancy book, the plot was way too predictable. The good guys did everything correctly, perfectly, every time, and the bad guys did exactly the opposite. There was never a change to this from beginning to end. Very dissapointing.

Readable but not very interesting, as the same scenario is repeated over and over: move the sub, then shoot torpedoes (but sometimes a Harpoon missile) and sink an enemy (or two...or three) then ... repeat ... repeat ... repeat ... until you fill all the pages of the book.

An entertaining read but not what you expect from Clancy; game or otherwise. This book is what fast food is to a gourmet meal. Lots of action but unbelievable and most disappointing was the lack of detail that goes into a typical Clancy book.

Read it but disappointed.

Mr. Clancy wrote this book as a companion/complement to a submarine video game, and that is exactly what it is.

~400 pages of video game action. Any 100 pages might appeal to Larry Bond fans, but the scenarios just got repetitious.

But hey, it was not so dull that I did not finish.

This is not up to Clancy's usually well written and intrigueing stories. This was essentially a submarine commander's log of a war patrol. His character development was lacking.
