AN/APQ-13
Radar AN/APQ-13 adalah sebuah radar scanning tanah yang dikembangkan oleh Bell Laboratories, Western Electric, dan MIT sebagai model perbaikan dari radar udara H2X, sendiri dikembangkan dari radar scanning tanah pertama, radar Inggris H2S. Itu digunakan pada B-29 selama Perang Dunia II di Pasifik untuk pengeboman daerah ketinggian, pencarian dan navigasi. Perhitungan pengeboman bisa dilakukan oleh prediktor dampak. Sebuah unit rentang diizinkan tingkat akurasi yang tinggi dalam beacon. Radar dioperasikan pada frekuensi 9375 ± 45 megahertz dan digunakan penerima superheterodyne.
