Seeing them occupied, you beckon Hate over to one side, confident in the noise of gunfire keeping your headset-equipped conversation private. "Is Willie always shooting low like that?"
"Only when she's not shooting high. And to either side."
"That's just jerking," you say, and Hate nods. "But why can't she get the range right?"
Hate shrugs. "Because she's shit at it?"
You shake your head. "No... no, that's not it. You saw her squinting through that face-shield-"
"That's non-negotiable," Hate says firmly. "You saw her damn near drop the thing; it's saved her from shooting herself in the face before."
"That's not my point. Everything about this range setup is based on optical rangefinders, and hers were never the best to begin with."
Hate raises an eyebrow. "They're not?"
"No. She's a Fletcher-class. They were equipped with a Mark 1 fire control computer, and most of the benefit came from the integrated fire control radar."
Hate seems to sag as realization hits. "Aaand we're making her determine distance to a silhouette on paper via parallax rangefinding."
"Right. Her optical rangefinder works well enough, but she never used it much during the war, and it was slower, and-"
"Right, right," Hate says, thinking. "I see what you're driving at."
"Damn shame, too," you sigh. "The radar feeds the data directly to the analog computer, so you didn't need guys peering at lines in a telescope before fiddling with dials to input the data. It could compute solutions and lay guns damn near as fast as you could point the director."
"Eh, really?"
"Yeah. And for the most part the radar's accuracy only increased as range closed, unlike parallax range-finding."
