SSN - Tom Clancy [70]
The crew was silent after the captain finished talking on the 1MC. Each and every man on board Cheyenne realized that this could be a long war unless they put more rounds into the Chinese, both above and beneath the surface of the sea, and they couldn't help wondering when Columbia and Bremerton would be sent to help. Being kept informed was the name of the game on board Cheyenne, and the executive officer had passed on the sister ship information at quarters prior to getting under way.
Cheyenne's second patrol area was located two hundred nautical miles south-southeast of Macclesfield Bank, a spot that shoaled rapidly from over two thousand fathoms to depths of less than forty feet. The transit there was fast and silent and uneventful.
On arrival near the southwest corner of the area, the captain ordered the OOD to launch an SSXBT. This submarine bathythermograph device was designed to rise to the surface and then drop to the bottom, collecting data on temperature versus depth information through the water column. The SSXBT would send this data back over a thin wire, similar to the torpedo guidance wire, to an onboard recorder in the control room. The information from the SSXBT would be input to the BSY-1 for use by the sonar and fire-control systems. It also would provide layer depth information so that Cheyenne could effectively hide beneath the layer, or even a second, deeper layer.
Mack had not had time upon arrival in the first patrol area to obtain the SSXBT information. Cheyenne had encountered the two Alfas too quickly. But that wouldn't be the case this time. He was planning the long-range shots now, and the information collected by the SSXBT would be vital to their accuracy. Cheyenne would get more SSXBT information at other locations, just in case horizontal gradients were present that could significantly affect the fire-control solution.
Three of the four planned SSXBT "shots" had been completed when the OOD informed the captain that sonar had gained weak, but slowly closing, Alfa-like tonal contacts to the north, possibly three separate contacts.
Mack acknowledged the information, but he didn't like what it meant. These contacts couldn't have been the Alfas from the south, so Russia really was dumping nuclear attack submarines on China.
Minutes later, while he was talking with the executive officer outside the exec's stateroom, the OOD told Mack over the exec's sound-powered phone that he had incoming flash VLF traffic over the floating wire. Mack and the executive officer proceeded to the radio room forward of the control room.
Bad timing, Mack thought as he read the message. As if the inbound Alfas weren't enough, Cheyenne had just received orders to prepare to launch their Tomahawks. To do that, they would have to proceed to periscope depth to copy the IPAC Tomahawk targeting data over SSIXS.
Mack didn't like it. Ideally, they would do that quickly, get to periscope depth, copy lengthy SSIXS traffic, and get back down before they lost the long-range shot advantage against the Alfas. Unfortunately, this situation was far from ideal. Launch directives were also coming in over the floating wire, and those launch directives wouldn't allow him that luxury. Cheyenne was to remain at periscope depth and launch all twelve missiles as soon as the download was complete and pre-Palawan Island waypoints had been inserted into the CCS Mk 2 console. Mack didn't like it, but his orders didn't give him any choice. Wasting no time, he ordered the OOD to take Cheyenne up to periscope depth.
As soon as Cheyenne started copying the targeting data, the captain ordered, "Man battle stations, missile," then explained the situation to the crew. Cheyenne was to launch the TLAM-Cs to take out aircraft on the ground
