Modular Segmented SRBs

Gene looked at the reports and sighed. How did it come to this... again??? Gathering everything together, he stomped into the main briefing room, looked around coldly at everyone, then slammed the pile of reports onto the table, sending papers flying all across the room. "The budget projects for the next project are out of sight.... Again!!!" "It's those darned SRBs, they're too big..." Bill replied meekly. "They're still cheaper than making complete rockets" Bob continued even more softly... Gene just glared... "I have an idea," von Kerman raised his hand, and all eyes turned on him. "Why don't we make the SRBs the same way we make rockets; in parts" Gene looked exasperated. "Because rockets use LIQUID FUEL!!!" Werhner took a deep breath and smiled slyly.... "So?" Gene rolled his eyes, "How do you intend to fuel the SRBs on the pad??? They ARE solid, you know!" von Kerman just smiled and continued unphased. "Why don't we make standard sized modules, fill them with the solid propellant, and then stack them together. Just like we stack the liquid tanks" Gene took a deep breath. Everyone shrank back, expecting an explosion. No explosion happened, other than Gene turning a bit greener. "Ummm, explain yourself", Gene grumbled, then sighed in resignation. "Please". "The thrust of an SRB is determined by how long it is." Von Kerman explained "So, we stack segments to get the desired length... and Voila'" Everyone watched amazed as Gene's eyes crisscrossed a few times, then slowly focused back on von Kerman. "You have a week to make it happen..."
