Section 3: Mathematical & Attrition Rate Calculations

1. A strategic bombing force dispatches N₀ = 250 heavy bombers on a mission. If the anti-aircraft defense and interceptor attrition rate per sortie is a = 4.8%, calculate the number of surviving aircraft N_s after 1 sortie and the total aircraft lost L.
   Answer:
   N_s = N₀ × (1 – a)
   N_s = 250 × (1 – 0.048) = 250 × 0.952 = 238 surviving bombers.
   Aircraft Lost L = N₀ – N_s = 250 – 238 = 12 bombers lost.
2. An air wing conducts an ongoing campaign over n = 5 sequential sorties. Starting with N₀ = 100 aircraft and experiencing a constant loss rate of a = 3% (0.03) per sortie, calculate the remaining force N₅ at the conclusion of the 5th mission.
   Answer:
   N_n = N₀ × (1 – a)ⁿ
   N₅ = 100 × (1 – 0.03)⁵ = 100 × (0.97)⁵
   N₅ = 100 × 0.8587 = 85.87 ≈ 85 aircraft remaining (15 aircraft lost cumulatively).
3. A reconnaissance aircraft flies at a constant true airspeed V = 480 knots at an altitude of 30,000 feet. Calculate the time t (in minutes) required to cover a target reconnaissance corridor of distance D = 360 nautical miles.
   Answer:
   Time t (hours) = D / V = 360 / 480 = 0.75 hours.
   Time t (minutes) = 0.75 × 60 minutes = 45 minutes.
4. During a military airlift mission, a transport fleet must move 1,200 metric tons of supplies to a forward operating base. Each transport aircraft has a max payload capacity C = 30 metric tons per flight. If each aircraft can perform 2 round-trip sorties per day, calculate the minimum number of aircraft A required to complete the supply delivery in 2 days.
   Answer:
   Total sorties needed = Total Cargo / Capacity = 1,200 / 30 = 40 total sorties.
   Sorties per aircraft over 2 days = 2 sorties/day × 2 days = 4 sorties per aircraft.
   Required Aircraft A = 40 total sorties / 4 sorties per aircraft = 10 transport aircraft.
5. An unguided bomb dropped from an altitude of h = 2,000 meters in a vacuum would take time t to hit the ground under gravitational acceleration g = 9.8 m/s². Calculate the free-fall time t using standard kinematic equations.
   Answer:
   h = 0.5 × g × t²
   2,000 = 0.5 × 9.8 × t² = 4.9 × t²
   t² = 2,000 / 4.9 ≈ 408.16
   t = √(408.16) ≈ 20.2 seconds.
6. A squadron of 12 fighter jets consumes fuel at an average rate of R = 2,400 kg per hour per aircraft during cruise. Calculate the total fuel F_total in metric tons required for the squadron to execute a 3.5-hour combat air patrol (CAP) mission.
   Answer:
   Fuel per aircraft = 2,400 kg/hr × 3.5 hrs = 8,400 kg.
   Total fuel for 12 aircraft = 12 × 8,400 kg = 100,800 kg.
   In metric tons (1 metric ton = 1,000 kg): F_total = 100,800 / 1,000 = 100.8 metric tons.
7. To achieve a target destruction probability P_D = 95% (0.95) against a reinforced radar site, planners calculate single-shot kill probability for a specific weapon as P_k = 0.40. Using the formula P_D = 1 – (1 – P_k)ⁿ, solve for the minimum integer number of weapons n that must be launched.
   Answer:
   1 – P_D = (1 – P_k)ⁿ
   1 – 0.95 = (1 – 0.40)ⁿ → 0.05 = (0.60)ⁿ
   Take natural logarithms: ln(0.05) = n × ln(0.60)
   -2.9957 = n × (-0.5108)
   n = -2.9957 / -0.5108 = 5.86.
   Rounding up to the next whole integer: n = 6 weapons required.
8. An early radar array operating during World War II detects an incoming bomber formation at a range R = 120 miles. If the bombers are flying at a ground speed S = 240 mph directly toward the target, calculate the total early warning time T_w in minutes available for fighter interceptors to scramble.
   Answer:
   T_w (hours) = Range / Speed = 120 / 240 = 0.5 hours.
   T_w (minutes) = 0.5 × 60 minutes = 30 minutes of warning time.
