SUBJECTIVE READER REVIEW WITH PLOT SPOILERS FOLLOWS:
If this was Don Bentley's last contribution to the Clancy Universe before taking over the Vince Flynn Universe, he went out with a bang! Though not as action packed as 'Target Acquired,' 'Weapons Grade' avails itself quite nicely with a storyline with more twists and turns I had to read it twice to catch everything! I don't ever do that either. For once, Jack Ryan Jr. is innocent by standards when trouble lands in his lap.
Escaping their Campus world for a little privacy and relaxation, fiancés Jack and Liseanne Robertson head down to Austin, Texas, to meet up with her college roomie Karlie Dills, and after getting bombed at a bar that's the last we hear about Karlie. Jack heads off to College Station for a football game and on the way back stops to assist a driver whose vehicle was crashed in small town Briar Woods. Oops, that did it, Jack pissed somebody off and there will be hell to pay!
From this inauspicious beginning it takes about 250 pages to finally get the 25,000-foot view of the terrain, but Jack has stumbled across a very complex conspiracy to snatch a top secret unmanned aerial vehicle, the Corvair UCAV, by having it fly to Cuba as its interim stop from the Skunkworks Fab Plant in Palmdale, California. Jack becomes the center of the 'ground' battle to stop the heist, while a retired USAF Colonel Bob, call sign Lorenzo, is called back for a final flight in his old bird, the SR-71 Blackbird, and becomes the center of the 'air' battle. By way of explanation, the SR-71 is the only aircraft ever built that can 'shadow' the Mach 5 UCAV during its prototype acceptance flight, but things go very badly.
The ground battle is being pursued by mercenaries hired by Iranian spy Yebo, the leaders of which are former South African Recces out for their last big merc job before retiring. Little do they know it will be permanent retiring until it's way too late. As Jack gets snatched in Briar Wood, awaking on railroad tracks with a train charging towards him, he endures the first of the beatings which finally leave him a bruised and partially broken human in the end. In the middle he sets up the mercs and gets off a mayday to the Campus, resulting in a worldwide Mayday for all operators to converge on Texas. His Ranger buddies Carey and Jad are the only ones who can get to him, and they turn out to be just enough to make it out alive.
After making the Mayday call to Gavin Bierry, he purposely alerts the mercs to his location by turning on one of their phones, then hires Isaac and Kyle and their Texas Hog Hunters helicopter to tail the bad guys when they come to snatch him a second time at a seedy rural Texas motel. To Jack's good fortune, Issac and Kyle are former SPECOPs operators, so there's four seasoned veterans plus Liseanne to fight the ground battle.
Much to Colonel Bob's surprise, the UCAV doesn't head due east per its mission profile, but turns south, ultimately doing slow circles in the sky above Widow's Peak, Texas, which has become the mobile command post for the mercs. Using a back door in the systems comms maintenance feed, the mercs send a huge ballon up with a controller's cab that links up with the UCAV and downloads the new mission profile. Just as it nearly completes transmission, Jack, riding in the Hog Hunter's chopper, shoots up the balloon antenna that's making the link to the UCAV.
In what had to be the longest National Security Council meeting in modern history, Colonel Bob is saved from intercepting the UCAV with the Blackbird only when Jack Junior disables the mercs illicit transmitting capability. Bentley seems to think that Jack Jr. must be black and blue and on death's doorstep at the conclusion of any Jack Ryan novel, but let me tell ya, it's not one you wanna miss!
